An article comprising wood can be preserved by applying to the wood an effective amount for the preservation of the wood of a polymeric phenol sulfide having a tri- or higher sulfide bridge therein, which can be a polymeric alkyl phenol sulfide, such as one containing an alkyl group containing from one to about four carbon atoms in the alkyl group contained therein of the following formula, where R is the alkyl group,:

Wood preservation utilizing polymeric phenol sulfide

A process for the manufacture of a polymeric phenol sulfide, which can be a polymeric alkyl phenol sulfide, such as one containing an alkyl group containing from one to about four carbon atoms in the alkyl group contained therein of the following formula, where R is the alkyl group,:

Process for making polymeric phenol sulfide

An article comprising wood can be preserved by applying to the wood an effective amount for the preservation of the wood of a preservative composition consisting essentially of a polymeric phenol sulfide having a tetra- or higher sulfide bridge therein alkyl phenol sulfide, such as one containing an alkyl group containing from one to about four carbon atoms in the alkyl group contained therein of the following formula, where R is the alkyl group,: ##STR1## where R is alkyl, m is from 1 to 3, n ranges from about 2 to about 10, and x is about 4.

Coated fabrics, for example, are disclosed comprising an open weave substrate (e.g., of polyester resin) coated with an adhesion promoting film comprising a vinyl chloride polymer and a carbon monoxide-propylene copolymer (e.g., having a molecular weight of from about 400 to about 1,000).

Substrate with adhesion promoting film comprising vinyl chloride polymer

Polyketone polymers can be stabilized and rendered more processable by the inclusion of a liquid crystalline diglycidyl compound, e.g., the diglycidyl ether of a 1,4-bis(p-hydroxybenzoyloxy) cyclohydrocarbon.

Liquid crystalline epoxy resin as additive for polyketone polymers

Polyvinyl chloride resin can be plasticized with a carbon monoxide-propylene copolymer. Since the copolymer is soluble in organic solvent, it and the polyvinyl chloride can be dissolved in an organic solvent and then cast to form a film. The copolymer can be a liquid, relatively low molecular weight material, which can be heat blended with the resin along with a smaller amount of a conventional external plasticizer for the resin.

Plasticization of polyvinyl chloride with carbon monoxide-propylene

Aqueous-based adhesive compositions having good adhesion to a non-polar polymeric surface and to cellulosic materials comprise a dispersion of an adhesive comprising an N-vinyl lactam polymeric resin, a tackifier for such adhesive, and an effective amount of an ethylene/vinyl acetate copolymer emulsion stabilizer for the resin and tackifier. Preferred N-vinyl lactam polymeric resins are vinyl pyrrolidone/vinyl acetate copolymers and a preferred class of tackifier are the rosin ester tackifiers.

Aqueous adhesive composition containing N-vinyl lactam resin, tackifier,

A novel adhesive exhibiting low outgassing upon exposure to high temperatures is disclosed. The instant adhesive comprises: (a) a soluble polyimide resin, (b) a solvent for said polyimide resin, (c) an epoxy resin, (d) a cross-linking agent reactive with the polyimide solvent of (b), and (e) a catalyst which accelerates the reaction between (b) and (d). Optionally, the adhesive may also contain a conductive material. A process for making the adhesive is also disclosed.

A novel adhesive exhibiting low outgassing upon exposure to high temperature is disclosed. The instant adhesive comprises: (a) a soluble polyimide resin, (b) a solvent for said polyimide resin, (c) a tackifier, (d) an epoxy resin, (e) a hardener for said epoxy resin, (f) a catalyst which catalyzes the reaction between the epoxy and hardener, (g) a cross-linking agent reactive with the polyimide solvent of (b), (h) a catalyst which accelerates the reaction between (b) and (g), and (i) a filler material. Optionally, the adhesive may also contain a conductive material. A process for making the adhesive is also disclosed.

Thermally stable adhesive

Film forming compositions are disclosed which can be utilized to make vapor barrier films having low water vapor transmission, good flame retardancy and low smoke generation characteristics. The compositions of the present invention contain an internally plasticized vinyl chloride copolymer resin as a major polymer component, rather than an externally plasticized vinyl chloride polymer, or a blend of a vinyl chloride polymer and chlorinated polyethylene.

Building/vapor barrier combination

A laminate for the protection of motor vehicle bodies from abrasion and corrosion damage which has a film component comprising an internally plasticized vinyl chloride copolymer resin and an effective amount of a polymeric additive for improving the flexibility of the film and an adherent layer of pressure sensitive adhesive.

Laminate for the protection of motor vehicle bodies

The blending of an effective amount of an ethylene/carbon monoxide polymer with an internally plasticized vinyl chloride copolymer improves the low temperature flexibility and color stability during ageing of films made from the resulting blend as compared to films containing the internally plasticized resin in the absence of the ethylene/carbon monoxide polymer.
