Abstract
Crosslinkable poly(arylene sulfide) oligomers are prepared by reaction of a dihaloaromatic compound, a sulfur compound that is reactive with halo organic compounds to form thioethers, and an end cap monomer corresponding to the formula: A.sub.i --Ar--X where A is an alpha, beta-unsaturated hydrocarbon moiety that is subject to step growth reaction by chemical activation, or by thermal activation at temperatures substantially in excess of the temperature of formation of the oligomer. Both linear and multidimensional oligomers are disclosed.
