Abstract
Способ получения полимеров или сополимеров изобутилена каталитической полимеризацией его или сополимеризацией с изопреном от -40 до -100С в среде хлорсодержащего углеводородного растворителя в присутствии антиагломератора, отличающийся тем, что, с целью увеличения продолжительности работы реактора полимеризации, в качестве антиагломератора применяют от 0,005 до 9,15% (от веса мономеров) кремнийсодержащие соединения, выбранные из группы, содержащей аэросил, полиэтилгидридсилоксан с мол.в. от 1110 до 1480, полиметилсилоксан с мол. вес. от 754 до 828, полиметилсилоксан с мол.в. от 25000 до 27000, полиэтилсилоксан с мол.в. от 552 до 1470.The method of producing polymers or copolymers of isobutylene by catalytic polymerizing it or by copolymerization with isoprene from -40 to -100 ° C in a chlorine-containing hydrocarbon solvent in the presence of an anti-agglomerator, characterized in that, in order to increase the duration of the polymerization reactor, from 0.005 to 9 15% (by weight of monomers) silicon-containing compounds selected from the group containing aerosil, polyethylsiloxane with mol. from 1110 to 1480, polymethylsiloxane with mol. weight. from 754 to 828, polymethylsiloxane with mol.v. from 25,000 to 27,000, polyethylsiloxane with a mol.v. from 552 to 1470.
