Abstract
An enhancement of the bulk and hand of carpeting and carpet fiber is made by treating with a terpolymer, particularly the terpolymer of (a) phenyl vinyl ether, (b) 2-(4-hydroxymethyl-phenoxy)ethyl vinyl ether, and (c) maleic anhydride.
Claims8
A process for the enhancement of bulk and hand of carpeting comprising applying to said carpeting an amount effective to enhance the bulk and hand of a terpolymer which is the reaction product of (a) phenyl vinyl ether, (b) 2-(4-hydroxymethyl-phenoxy)ethyl/vinyl ether, (c) maleic anhydride in proportions effective to enhance the bulk and hand of said carpeting.
A process for the enhancement of bulk and hand of carpeting comprising applying to said carpeting an amount effective to enhance the bulk and hand of a mixture of copolymers in proportions effective to enhance the bulk and hand of said carpeting said copolymers being (i) a copolymer of phenyl vinyl ether and maleic anhydride and (ii) a copolymer of 2-(4-hydroxymethyl-phenoxy)ethyl vinyl ether and maleic anhydride.
