Abstract
An arylene sulfide polymer and a process for preparing same by contacting a sulfur source, a cyclic organic amide and a dihaloaromatic compound to produce a polymerization mixture, polymerizing the polymerization mixture and recovering the arylene sulfide polymer wherein the process is conducted in the presence of a compound having the formula ##STR1## wherein X is selected from the group consisting of bromine and iodine, Y is a non-activating or deactivating group and is selected from the group consisting of ##STR2## R' and R" are hydrogen or an alkyl group having 1 to about 15 carbon atoms, and Ar' is selected from the group consisting of ##STR3##
