Claims
- 1. An ABS polymer comprising:
- (A) a graft copolymer formed by graft polymerizing styrene and acrylonitrile monomers onto an intially ungrafted, low gel diene rubber; and
- (B) a copolymer of said grafted monomers in which said grafted copolymer is dispersed; said diene rubber comprising 3 to 25% by weight of said polymer; the polymerized acrylonitrile content of said polymer being 27 to 40% by weight; said A and B simultaneously formed by continuous mass polymerization from a substantially uniform reaction composition.
- 2. The polymer of claim 1 wherein the particle size of said diene rubber in said polymer is from 0.1 to 10 microns.
- 3. The polymer of claim 1 wherein the particle size of said diene rubber is from about 0.8 microns to about 10 microns.
- 4. The polymer of claim 1,2 or 3 wherein said diene rubber comprises from about 14 to about 25% by weight of said polymer.
