Provided is a method for preparing a latex composition, comprising providing an ethylene copolymer comprising copolymerized units of ethylene and copolymerized units of at least one polar comonomer; dissolving the ethylene copolymer with one or more latex monomers to prepare a solution; mixing the solution with water; optionally adding a surfactant or protectant colloid to form an aqueous emulsion; and polymerizing the latex monomer in the emulsion to form a latex composition comprising the ethylene copolymer and a latex polymer. Further provided are the emulsion polymerization product and the mini-emulsion polymerization product of at least one ethylene copolymer substantially dissolved in at least one latex monomer, such as an acrylic, styrene or vinyl monomer. Finally, formulated products comprising or produced from the emulsion or mini-emulsion polymerization product and articles comprising or produced from the formulated products are provided.

Method of incorporating ethylene copolymers into latex

Provided herein is a plastisol composition comprising a halogenated polymer and an ethylene carbon monoxide copolymer that is dispersed or dissolved in a liquid plasticizer. A process for producing the plastisol composition is further provided.

Ethylene copolymer-modified plastisol

Exercise mat carrying strap

Disclosed is a laminar shaped article comprising a heterogeneous blend of (a) a composition comprising a vinyl halide or vinylidene halide polymer and optionally an ethylene copolymer containing carboxyl and/or carbon monoxide moieties, and (b) a polyolefin functionalized with a comonomer selected from the group consisting of maleic anhydride, maleic acid diesters, maleic acid monoesters, itaconic anhydride, itaconic acid diesters, itaconic acid monoesters, fumaric acid diesters, fumaric acid monoesters, or combinations thereof as a compatibilizer; and (c) a polyamide wherein the polyamide is present in the vinyl halide or vinylidene halide polymer as a multitude of overlapping layers.

Laminar articles with good hydrocarbon barrier

A product comprises or is produced from a substrate and optionally a thermal insulation wherein the substrate comprises or is produced from polyvinyl chloride and a liquid plasticizer; the substrate, the insulation material, or both is coated, laminated, coextruded, or applied with a barrier layer comprising an ionomer; and the substrate is in close proximity to the insulation material. Also disclosed is a process that can be used to prevent liquid plasticizer from migrating out of polyvinyl chloride product wherein the product is optionally in close proximity to a thermal insulation; the process comprises coating, laminating, coextruding, or applying a barrier layer disclosed above onto the surface, or a portion thereof, of the product or onto the insulation.

Product comprising ionomer and plasticizer

Disclosed are composite compositions and articles prepared from such composites. The composition comprises or is produced from cellulose material, thermoplastic polymer, and a compatibilizing agent which is the reaction product of polyvinyl butyral, having hydroxyl functionality, and a second polymer which comprises or is produced from polyvinyl butyral and a second polymer wherein the polyvinyl butyral comprises a hydroxyl functionality and the second polymer reacts with at least a portion of the hydroxyl functionality.

Composite comprising cellulose and thermoplastic polymer

The present invention relates to polyepoxy-polymer-linked-asphalt having enhanced properties made by reacting a glycidyl-functionalized ethylene copolymer with reactive asphalt, wherein the glycidyl-functionalized ethylene copolymer has a glycidyl-containing comonomer content of 5 weight percent or less and relatively high number average molecular weight characterized by a melt index of 4 grams/10 minutes or less measured in accord with ASTM D1238-65T, Condition E.

Expoxy functionalized ethylene copolymer asphalt reaction products

Promoting adhesion (without need for an adhesive) of polyurethane to polyvinyl chloride sheet plasticized with ethylene/carbon monoxide polymer by adding an effective amount of a phenolic resin; particularly novolac resins.

Adhesion promoter for PVC compounds

Binder compositions are disclosed that include silica aquasols having silica that is metal-modified to include a monolayer or less of a metal such as aluminum, tin, zinc or lead, and deionized to a pH of 2,5-7.0 and a water soluble polymer such as poly(vinyl alcohol). An adhesive that includes a silica aquasol, an oxygen-moiety containing polymer, and clay, the surface of the silica being modified to include a metal, and the silica aquasol being deionized to a pH of 2.5 to 7.
