A method for attracting cockroaches to an object or area, involving treating said object or area with a cockroach attracting composition containing a cockroach attractant effective amount of at least one compound selected from the group consisting of methyl, ethyl, propyl, or butyl esters of Csaturated or unsaturated carboxylic acids and mixtures thereof, and optionally a carrier material or carrier. A method for repelling cockroaches from ah object or area, involving treating said object or area with a cockroach repelling composition containing a cockroach repelling effective amount of at least one compound selected from methyl, ethyl, propyl, or butyl esters of Csaturated or unsaturated carboxylic acids or mixtures thereof, and optionally a carrier material or carrier.

A method for applying a barrier to structures to prevent the infiltration of pest species (unwanted organisms) uses a (e.g., coating) composition formed from a polyurethane (e.g., film-forming) polymer system and a pellet comprising a pesticide incorporated into a sorbent and dispersed in the polyurethane polymer system. The composition protects the structure by application either to the structure or to a pathway that leads to the structure. Advantageous polymer systems include polyurethanes rich in urea linkages and predominating in aliphatic and alicyclic backbones.

Sustained release pest control products and their applications

One aspect of the present invention is a sprayable composition for coating pipe for protecting it from one or more of root intrusion or root growth when the coated pipe is placed underground. Such sprayable formulation includes a 2,6-dinitroaniline herbicide; a polymer pellet impregnated with a 2,6-dinitroanililne herbicide-sorbed colloidal clay; and a film-forming polymer. Another aspect is pipe coated with the dried residue of a coating of a 2,6-dinitroaniline herbicide; a polymer pellet impregnated with a 2,6-dinitroaniline herbicide-sorbed colloidal clay; and a film-forming polymer, wherein the coated pipe is protected from one or more of root intrusion or root growth when the coated pipe is placed underground.

Methods and products to protect against root intrusion and plant and root growth

The present invention is directed to a method for reducing waste accumulation by using an environmentally degradable disposable material. The disposable material, which includes a hydroxycarboxylic acid-containing polymer, degrades hydrolytically during operative and disposal stages in a controlled manner such that the disposal degradation rate of the material is accelerated relative to the operative degradation rate of the material.

Degradation control of environmentally degradable disposable materials

A method for creating an wood destroying organism resistant coating is disclosed. The method involves spraying a structure with a mixture of a quick setting liquid monomer and a pesticide. The monomer, when cured, forms a bonded polyurethane coating upon the surface a structure which slowly releases pesticide over long periods of time. The method may be practiced as a two part system utilizing monomers and catalytic curing agents, and a one part system utilizing masked isocyanates.

Method for applying pesticides and repellents

Disclosed are degradable materials including molded products, laminates, foams, nonwoven materials, adhesives, coatings and films, and particularly packaging films. The materials are made using polydioxaneone polymers comprising at least two different dioxaneone-based repeating units. Preferred polymers are polydioxanediones. First repeating units have less carbon atoms in constituent groups extending from the polymer backbone than second repeating units. Physical characteristics and degradation of the materials can be varied by varying the choice and/or relative proportions of first and second repeating units in the polydioxaneone polymers. Methods for preparing polydioxaneone polymers that can be used in the manufacture of the materials are also discussed, as are suitable monomers and methods for preparing such monomers.

Degradable polydioxaneone-based materials

Disclosed are degradable materials which-include a nontoxic hydrolytically degradable polymer and nontoxic modifier, wherein the modifier is compatible with the polymer and the modifier is nonvolatile and nonfugitive. Also disclosed are processes for forming the various degradable materials, which include films, molded products, laminates, foams, powders, nonwovens, adhesives and coatings. The disclosed materials and processes are particularly useful for the production of commercial and consumer products in high volumes which are suitable for recycling after use or which are discarded into the environment in large volumes.

Degradable polymer composition

Methods for producing improved pipe structures for natural gas distribution pipelines produce a thin fibrous jacket or layer which can inhibit and prevent cracks in natural gas distribution piping by preventing surface scratches as well as by enhancing the pipe strength. Thermoplastic fibers are preferred in accordance with methods and structures of the present invention to facilitate the use of joining techniques and hot-tapping techniques common in the natural gas distribution industry. Non-woven, heat shrinkable fibers are also employed in sleeve structures to produce a protective fibrous jacket or layer.

Pipe designs using composite materials

Disclosed are products made of degradable materials which include a hydrolytically degradable polymer. The degradable materials can be internally or externally modified. The internally modified polymer composition has polymers modified by the use of comonomers having a relatively high molecular weight. The externally modified polymer composition includes a modifier, wherein the modifier is compatible with the polymer and the modifier is nontoxic, nonvolatile and nonfugitive. The various degradable materials include films, fibers, extruded and molded products, laminates, foams, powders, nonwovens, adhesives and coatings. The disclosed materials are particularly useful for the production of a variety of products in high volumes which are suitable for recycling after use or which are discarded into the environment in large volumes.

End use applications of biodegradable polymers

Disclosed is a novel integrated process for production of cyclic esters which includes recovery of starting materials, such as lactic acid from a dilute aqueous lactic acid-containing solution, by solvent extraction. The starting materials are then formed into cyclic esters by removal of water wherein the concentration of higher molecular weight oligomers is maintained below about 20 wt % of the reaction composition. The process further includes providing a recovery solvent for the reaction composition and separating the cyclic esters from the starting materials and higher molecular weight oligomers by liquid-liquid equilibrium separation. The present invention is further directed toward independent novel unit operations of the overall process. The present invention provides for the efficient production and recovery of cyclic esters due to integration of the various unit operations by use of appropriate solvents and recycle streams. In addition, high rates of conversion of starting materials and high rates of selective production of cyclic esters are achieved by appropriate control of process parameters.

Method to produce cyclic esters

The materials are made using polydioxaneone polymers comprising at least two different dioxaneone-based repeating units. Preferred polymers are polydioxanediones. First repeating units have less carbon atoms in constituent groups extending from the polymer backbone than second repeating units. Physical characteristics and degradation of the materials can be varied by varying the choice and/or relative proportions of first and second repeating units in the poldioxaneone polymers. Methods for preparing polydioxaneone polymers that can be used in the manufacture of the materials are also discussed, as are suitable monomers and methods for preparing such monomers.
