Polymerization catalyst and method for producing isobutylene-styrene copolymer using the same |
| abstract |
PROBLEM TO BE SOLVED: To provide a polymerization catalyst capable of producing a relatively low molecular weight isobutylene-styrene copolymer by high-temperature cationic polymerization in a high yield, and to provide an isobutylene-styrene copolymer using the catalyst. A manufacturing method is provided. SOLUTION: General formula (I) R 1 R 2 AlX (I) (R 1 and R 2 are an alkyl group having 1 to 10 carbon atoms or 7 carbon atoms) And X represents a halogen atom. A) a dialkylaluminum halide and a cocatalyst represented by An isobutylene-styrene copolymer optionally containing a metal halide, and a copolymer of isobutylene and styrene at a temperature of 10 ° C to 50 ° C in the presence of the catalyst to produce an isobutylene-styrene copolymer How to |
