Abstract

The invention belongs to the technical field of functional high polymer materials, aims to solve the problem of low impact strength of ABS resin in the prior art, and provides astyrene / acrylonitrile copolymer resin (ABS resin) toughened by A-DPE derivative / styrene / isoprene / butadiene copplymer integrated rubber, wherein the A-DPE derivative is a 1,1-diphenyl ethylene derivative monomer containing a silicon group, an amino group, a silicon group / amino group, a silicon-oxygen group and a silicon-hydrogen group; based on the mass of the ABS resin being 100%, the content of integrated rubber is 3%-35%, the content of acrylonitrile is 5%-45%, and the balance is styrene; and the number-average molecular weight of the ABS resin ranges from 10 * 10 <4> g / mol to 80 * 10 <4> g / mol. Functional sites are qualitatively, quantitatively and fixedly introduced into a rubber phase through an anionic polymerization method, so that uniform dispersion of the rubber phase is facilitated, ABS has excellent impact resistance, and meanwhile, the binding property and compatibility of the material and a polar additive are greatly improved.

Description

Technical field [0001] The present invention belongs to the field of functionalized polymer materials, and more particularly to a soluble poly-DPE derivative / styrene / isoprene / butadiene integrated rubber toughening ABS resin and its preparation method thereof. Background technique [0002] The ABS resin is usually a classic polybutadiene rubber or butadiene, a styrene copolymer rubber as a toughening agent, and the toughening agent is dissolved in styrene, acrylonitrile according to a certain ratio, using a thermal initiation or initiator. Method for initiation. After the rubber toughening agent was added, the anti-impact performance of the SAN resin was improved, but the above-mentioned general rubber as a toughening agent was difficult to obtain an ultra-high impact strength ABS resin, and the use of ABS alkene resin was limited to a certain extent. [0003] The ABS resin is usually a classic polybutadiene rubber or butadiene, a styrene copolymer rubber as a toughening age...
