Abstract

Provide rubber modified styrene-acrylonitrile resin. (ARS), which has three different types of rubber particles, the first type is the smaller particles produced by emulsion and Another type is the larger particles produced by emulsion. The third type of particle is the causative polymeric particle. Formed as a aggregated polymer consisting of at least 80 percent rubber-like polymeric substrates by weight of the monomer. The born diene is enough. Polymer, and which is made up of no more than 30% by weight of all rubber components contained within In the mixture of interest The resulting mixture has special characteristics. Particularly high luster item and reduced luster sensitivity. On changes in casting conditions
