<p>A process for the production of an arylene sulfide terpolymer is provided comprising reacting at least one alkali metal sulfide, at least one p-dihalo unsubstituted benzene, at least one polyhalo aromatic compound having more than two halogen substituents per molecule, at least one p-dihalo, alkyl substituted benzene, and at least one N-alkyl lactam. Another process is provided comprising first reacting an at least one alkali metal sulfide in hydrated form or in an aqueous mixture with at least one N-alkyl lactam to form a reaction product, thereafter heating the reaction product to form a dehydrated composition, then reacting the dehydrated composition with a mixture consisting essentially of at least one p-dihalo unsubstituted benzene, at least one polyhalo aromatic compound having more than 2 halogen atoms per molecule, at least one p-dihalo alkyl substituted benzene, and at least one member selected from the group consisting of (a) water in an amount of about 0.2 mole to about 2.5 moles per molecule of alkali metal sulfide under polymerization conditions for a time sufficient to produce the desired terpolymer. Arylene sulfide terpolymers are provided as products of the above processes.</p> |
