Abstract

The invention relates to the technical field of rubber toughening agents, and discloses a toughening agent composition and application thereof, HIPS resin, ABS resin and a preparation method thereof, the composition contains low cis-polybutadiene rubber and butadiene styrene rubber, and the content weight ratio of the low cis-polybutadiene rubber to the butadiene styrene rubber is (0.25-4): 1; the viscosity of the toughening agent composition in a 5 wt% rubber-styrene solution at 25 DEG C is 27-37 cp; the Mooney viscosity ML1 + 4 of the toughening agent composition at 100 DEG C is 40 to 50; the content of a butadiene structural unit in the toughening agent composition is 92-98wt%, and the content of styrene structural unit in the toughening agent composition is 2-8 wt%. When the toughening agent composition provided by the invention is used for an aromatic vinyl resin toughening agent, the aromatic vinyl resin with excellent surface gloss can be obtained while the impact strength is ensured, and the toughening agent composition has a wide industrial application prospect.

Description

technical field [0001] The invention relates to the technical field of rubber toughening agents, in particular to a toughening agent composition, the application of the toughening agent composition in the preparation of aromatic vinyl resins, a method for preparing HIPS resin and the method The prepared HIPS resin, a method for preparing ABS resin and the ABS resin prepared by the method. Background technique [0002] The selection of rubber species is a key technology in the toughening of continuous bulk aromatic vinyl resins. Low cis polybutadiene rubber has the advantages of uniform quality, moderate vinyl content, low gel content, low chroma, random distribution of molecular chain cis-trans 1,4 structure, and no transition metals. It is a continuous body Best toughening rubber for aromatic vinyl resins. [0003] According to the performance requirements of the resin, the microstructure, molecular weight and its distribution, Mooney viscosity and 5% by weight rubber-sty...
