Abstract
The present invention provides an article of manufacture comprising a textile substrate and a coating being a polymer comprising a non-aromatic unsaturated mono- or dicarboxylic ester monomer and an aliphatic conjugated diene monomer. An unsaturated mono- or dicarboxylic acid monomer or a monomer based on the half esters of the dicarboxylic acid monomer can also be included. In one embodiment, the present invention provides a method of preparing a textile substrate comprising applying to a surface of the textile substrate a coating, the coating being a polymer comprising a non-aromatic unsaturated mono- or dicarboxylic ester monomer and an aliphatic conjugated diene and heating the surface of the textile substrate to dry the coating.
Claims7
A method of recycling a textile substrate comprising:
- (a) providing a carpet comprising a primary backing, pile yarns extending from the front of the primary backing to form pile tufts, and having portions extending through the primary backing to the rear thereof;
- and a tuft-lock coating carried by the rear of the primary backing and securing the pile yarns to the primary backing, the tuft-lock coating being a styrene-free polymeric coating composition consisting essentially of from about 30 to 50 percent, by weight, of a non-aromatic unsaturated mono- or dicarboxylic ester monomer, from about 30 to 50 percent, by weight, of an aliphatic conjugated diene monomer, and from about 0.1 to 20 percent, by weight, of an unsaturated mono- or dicarboxylic acid monomer or a monomer based on a half ester of an unsaturated dicarboxylic acid;
- (b) reducing the size of the carpet substrate;
- and
- (c) extruding the reduced in size carpet to provide an extruded article of manufacture free of styrene.
