The invention relates to a new improved catalyst to produce random copolymers of one or more iso-olefin monomers and one or more para-alkylstyrene monomers. The invention also relates to an improved continuous slurry polymerization process to produce random copolymers using the improved catalyst system. The process is carried out in an anhydrous polymerization system containing a mixture of the monomers in a polar solvent along with a Lewis acid and a stabilizing initiator.

Abstract:
The invention relates to a new catalyst system that improves the heat transfer capability of a butyl reactor slurry process system in the production of random copolymers of one or more isoolefin monomers and one or more conjugated diene monomers in continuous slurry polymerization processes. The process is carried out in an anhydrous polymerization system containing a mixture of the monomers in a polar diluent along with a Lewis acid and a Cor greater initiator having a tertiary halide.

Abstract:
The invention relates to impact modifiers for polyamide compositions which improve the impact strength of the polyamides without adversely affecting the flexural modulus of the composition. The impact modifiers comprise blends of halogenated copolymers of a C. sub. 4 to C. sub. 7 isomonoolefin and an alkyl/styrene with a polyolefin.
