METHOD OF PREPARING BUTYL RUBBER

摘要

preparation of synthetic rubbers, more particularly butyl rubber used in petrochemical industry. SUBSTANCE: process of copolymerization of monomers is carried out at total content of protonated complexes from 5 to 45 % in catalyst, ratio of content of protonated complex based on alkylaluminum dichloride to content of protonated complex based on alkyl aluminum chloride ranging from 0: 1 to 0.5:1. EFFECT: improved quality of rubber, greater efficiency and lower stock losses. 1 dwg, 1 tbl
