Abstract
A process for the production of arylene sulfide polymers is provided which comprises subjecting a mixture of at least one sulfur source, at least one organic monohalo compound, at least one polyhalo-substituted aromatic compound and at least one polar organic compound to polymerization conditions sufficient to produce the arylene sulfide polymer. The organic monohalo compound can be added at any time prior to substantial completion of polymerization to provide arylene sulfide polymers of increased extrusion rate.
Claims21
A process for preparing arylene sulfide polymer comprising:
- (a) admixing at least one sulfur source, at least one polyhalo-substituted aromatic compound, at least one polar organic compound and at least one organic monohalo compound selected from the group of compounds represented by the formulas:
- ##STR6## wherein X' is a halogen selected from the group consisting of fluorine, chlorine, bromine and iodien;
- R is selected from the group consisting of hydrogen and an alkyl group of 1-4 carbon atoms;
- and Z is an activating group selected from the group consisting of ##STR7## where R' is selected from the group consisting of phenyl, an alkyl radical of 1-12 carbon atoms, phenyl to the ring bearing X' by a valence bond or an alkylene bridging group of 1-12 carbon atoms, and an alkyl radical of 1-12 carbon atoms attached to the ring bearing X' by a valence bond or an alkylene briding group of 1-12 carbon atoms and
- (b) subjecting said admixture to polymerization conditions sufficient to produce a polymerization reaction mixture comprising said arlyene sulfide polymer.
A process for preparing arylene sulfide polymer comprising
- (a) admixing at least one sulfur source, at least one polyhalo-substituted aromatic compound, and at least one polar organic compound to form an admixture;
- and
- (b) subjecting said admixture to polymerization conditions sufficient to product a polymerization reaction mixture comprising said arylene sulfide polymer wherein there is added to said polymerization reaction mixture after polymerization commences but prior to substantial completion of polymerization at least one organic monohalo compound selected from the group of compounds having the formulas:
- ##STR11## wherein X' is a halogen selected from the group consiting of fluorine, chlorine, bromine and iodine;
- R is selected from the group consisting of hydrogen and an alkyl group of 1-4 carbon atoms;

A process for preparing arylene sulfide polymer comprising adding, prior to substantial completion of polymerization, at least one organic monohalo compound to a polymerization reaction mixture comprised of at least one sulfur source, at least one polyhalo-substituted aromatic compound, and at least one polar organic compound;
- wherein said organic monohalo compound is selected from the group of compounds represented by the formulas:
- ##STR16## wherein X' is a halogen selected from the group consisting of fluorine, chlorine, bromine and iodine;
- R is selected from the group consisting of hydrogen and an alkyl group of 1-4 carbon atoms;

- ##STR18## wherein X' is a halogen selected from the group consisting of fluorine, chlorine, bromine and iodine;
- R is selected from the group consisting of hydrogen and an alkyl group of 1-4 carbon atoms;
- and Z is an activating group selected from the group consisting of ##STR19## where R' is selected from the group consisting of phenyl, an alkyl radical of 1-12 carbon atoms, phenyl attached to the ring bearing X' by a valence bond or an alkylene bridging group of 1-12 carbon atoms, and an alkyl radical of 1-12 carbon atoms attached to the ring bearing X' by a valence bond or an alkylene bridging group of 1-12 carbon atoms.
