TREATMENT OF EPOXIDATED UNSATURATED ISOOLEFIN COPOLYMERS Russian patent published in 2021 - IPC C08J3/24 C08K5/04 C08F8/04 C08F210/12 

Abstract RU 2742983 C2

FIELD: chemistry.

SUBSTANCE: invention relates to methods of treating epoxidated unsaturated isoolefin copolymers and products made therefrom. Method of producing a cross-linked polymer involves contacting an epoxidated unsaturated isoolefin copolymer with a catalytic amount of an acid in the absence of a solvent. Method of producing a hydroxylated unsaturated isoolefin copolymer involves contacting an epoxidated unsaturated isoolefin copolymer with a catalytic amount of an acid in the absence of a solvent. Epoxidated unsaturated isoolefin copolymer contains repeating units derived from isobutene and repeating units derived from isoprene.

EFFECT: invention increases creep rate of cross-linked epoxidated rubber.
