Abstract
The reactor used to destroy and modify polyisobutylene in the laboratory has been made of pyrex glass. For the first time, Friedel-Crafts catalysts were found to be the initiators of a radical chain-chain mechanism for the destruction of polyisobutylene. Based on this mechanism, it has been modified with polar monomers (acrylonitrile and vinilacetate). This creates conditions for the production of new types of copolymers. At the same time, the destruction of polyisobutylene with the participation of Fridel-Krafts catalysts has been fully proven to be the initiator of the radical-chain mechanism. Polyisobutylen polyacrylonitrile (PIB-PAN) and polyisobutylene polyvinyl acetate (PIB-PAV) copolymers obtained are suitable raw materials for the production of various types of composite products. One of the main issues of chemical technology in the article is the transition of processes from a laboratory experimental plant to an industrial production facility. The problem set have been solved, mathematical calculations of the studied processes have been carried out, the basic technological scheme of modification of polyisobutylene with polar monomers acrylonitrile and vinilacetate and production of compositions based on them have been reflected.
