Abstract

In order to solve the problems of poor impact resistance and the like of the resin in the prior art, the invention provides the ultrahigh impact strength HIPS resin containing DPE derivative, butadiene and styrene star copolymer block, and the HIPS resin is styrene / [(SN-SBR)-BR] n-C copolymer resin; SN-SBR is a DPE derivative, butadiene and styrene copolymer block, BR is a butadiene homopolymer block, and C is a polyfunctionality alkyl lithium initiator residue; in the (SN-SBR) 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-SBR) block to the BR block is (10 / 90)-(90 / 10); on the basis that the mass of the HIPS resin is 100%, the content of [(SN-SBR)-BR] n-C is 3%-35%.

Description

Technical field [0001] The present invention belongs to the field of high molecular material synthesis and preparation techniques, and in particular, the HIPS resin and preparation method of DPE derivatives, butadiene, styrene star copolymer blocks are involved. Background technique [0002] Due to the problem of multiple lithium in synthesis and refining, it has not yet formed industrialization. The multithium initiation method is to initiate polymerization with an anionic polymerization method using an anionic polymerization method to form a star block polymer with an anionic polymerization method, and the key problem of the method is the synthesis of multi-functional group organisms. Beijing Yanshan Petrochemical Research Institute applied for a number of patents in the development of the star block copolymer of the multiling system, using multi-functional group organized lithium initiators to initiate styrene, isoprene, butadiene, other conjugated diene A series of star block...
