Abstract
The binder composition for nonwoven products comprising a vinyl chloride-ethylene copolymer emulsion and up to 25 wt %, based on emulsion solids, of a polyamine containing 5 or 6 member N-heterocyclic moieties prepared by the polymerization of at least one diallylamine of the formula ##STR1## where R is hydrogen or a C.sub.1 -C.sub.4 alkyl group and R' is hydrogen or a methyl group.
Claims16
A binder composition for nonwovens comprising a chlorine-containing polymer which is a vinyl chloride homopolymer, a vinyl chloride copolymer, a vinylidene polymer or a chlorinated acrylic polymer and, as an amine crosslinking agent , up to 25 wt. % polyamine polymer which is the product of the polymerization of at least one diallylamine of the formula ##STR4## where R is hydrogen or a C.sub.1 -C.sub.4 alkyl group and R' is hydrogen or a methyl group.
