Title:
MULTI-COMPONENT COPOLYMER, PREPARATION METHOD THEREFOR, AND USE THEREOF, AND HALOGENATED BRANCHED BUTYL RUBBER, PREPARATION METHOD THEREFOR, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/067013
Kind Code:
A1
Abstract:
The present invention relates to the technical field of rubber preparation, and disclosed are a multi-component copolymer, a preparation method therefor, and use thereof, and a halogenated branched butyl rubber, a preparation method therefor, and use thereof. The multi-component copolymer comprises: a structural unit A, a structural unit B, and a structural unit C, wherein the structural unit A has a phase structure represented by formula (1), the structural unit B has a phase structure represented by formula (2), and the structural unit C has a phase structure represented by formula (3); wherein R1, R2, R3, R4, R5, R6, R7 and R8 are each independently hydrogen or a C1-C10 phase linear chain or branched alkyl; X is halogen, and n is any integer of 1 to 10; the phase tail end of the multi-component copolymer contains a phase structural unit from a conjugated diene. According to the present invention, the halogenated branched butyl rubber is prepared by taking the multi-component copolymer as a grafting agent, so that an effective damping temperature range and the phase stability of the damping performance of the halogenated branched butyl rubber are improved.
