METHOD OF SYNTHESIS OF COPOLYMER OF BURADIENE WITH ISO-BUTYLENE Russian patent published in 1998 - IPC

Abstract RU 2109760 C1

FIELD: technology of high-molecular compounds. SUBSTANCE: invention relates to methods of synthesis of copolymers of butadiene with iso-butylene using Lewis acid-base catalysts. Method involves copolymerization of indicated monomers in aromatic or aliphatic solvent by cationogenic catalysts based on Lewis acids. Crude recovery butadiene-butylene fraction of CKД rubber production is used as a basic monomer. Method can be used in chemical industry. EFFECT: simplified method of synthesis. 1 tbl
