Abstract

In order to solve the problems of poor impact resistance and the like of resin in the prior art, the ABS resin containing DPE derivatives, butadiene, isoprene and styrene star-shaped blocks is provided, and the ABS resin is styrene / acrylonitrile / [(SN-SIBR)-BR] n-C copolymer resin; SN-SIBR is a copolymer block of a DPE derivative, butadiene, isoprene and styrene, BR is a butadiene homopolymer block, and C is a polyfunctionality alkyl lithium initiator residue; in the SN-SIBR block, the butadiene content is 5 to 80 percent, the isoprene content is 5 to 80 percent, the styrene content is 5 to 50 percent, and the DPE derivative content is 0.5 to 20 percent; the ratio of the SN-SIBR block to the BR block is (10 / 90)-(90 / 10); based on the mass of the ABS resin being 100%, the content of acrylonitrile is 5%-45%, and the content of [(SN-SIBR)-BR] n-C is 3%-35%.

Description

technical field [0001] The invention belongs to the technical field of polymer material synthesis and preparation, in particular to a class of ABS resin containing DPE derivatives, butadiene, isoprene and styrene star copolymer blocks and a preparation method. Background technique [0002] Styrene-isoprene-butadiene rubber (SIBR) is an ideal integrated rubber with better comprehensive performance. It has a good balance between rolling resistance and traction performance. It is a promising new type of tread rubber. my country is rich in C5 resources, but the problem of its comprehensive utilization has not been completely resolved. As an important component of C5, isoprene (I) has a large potential yield. Therefore, solving the problem of comprehensive utilization of isoprene (I) is a very realistic subject in the field of synthetic materials. Furthermore, due to the very limited natural rubber resources in my country, it is difficult to meet domestic demand, and isoprene r...
