Abstract
Branched arylene sulfide polymers of low melt flow are produced by employing (1) a p-dihalobenzene, (2) a polyhalo aromatic compound having more than two halogen substituents per molecule, (3) an alkali metal sulfide, (4) an N-alkyl lactam, and (5) controlled amounts of water in the presence or absence of a sodium carboxylate. The resulting polymers without prior curing can be fabricated into shaped products having desirable properties.
