Abstract of the Disclosure In a first embodiment, arylene sulfide resins, are prepared by contacting, during a polymerization process, reactants comprising: (a) a first monomer source consisting of a p-dihaloaromatic compound, (b) a second monomer source comprising a o-dihaloaromatic compound. The first monomer source is present, prior to the initiation of polymerization, in an amount from about 90 to about 99.9 mole percent; and, the second monomer source is present, prior to the initiation of polymerization, in an amount from about 0.1 to about 10 mole percent. These mole percentages are based on the molar sum of (1) the first and second monomer sources present prior to the initiation of polymerization and (2) any component of the second monomer source, introduced after the initiation of polymerization. In a second embodiment, articles of manufacture are formed from the arylene sulfide resins prepared in the first embodiment. In a third embodiment, a process is provided for forming articles of manufacture consisting of: (a) preparing an arylene sulfide resin comprising first recurring units consisting of aromatic structures having the form: Image and second recurring units comprising aromatic structures having the form: Image wherein the first recurring units are present in an amount from about 90 to about 99.9 mole percent; and, the second recurring units are present in an amount from about 0.1 to about 10 mole percent, said mole percentages are based on the total recurring units present; and (b) forming an article of manufacture from the arylene sulfide resin.
