摘要： High impact polystyrene resins are provided having a surprisingly good combination of toughness and gloss characteristics. Such resins contain small (i.e. 0.1 to 0.4 micron) capsule morphology rubber particles in combination with relatively small (i.e. 0,25 to 1 micron) entanglement morphology rubber particles. It has been found that such resins are capable of providing izod impact strength values in the range of 2.5 to 3.5 ft-lb/in (133.4 to 186.7 J/m) and higher at an overall volume average rubber size of less than 0.4 micron with corresponding gloss values in excess of 90 percent.

摘要： The present invention is a continuous process for producing a rubber-reinforced polymer composition derived from a vinyl aromatic monomer, using a single reactor to produce a prepolymer composition containing dispersed rubber particles and to mix the prepolymer composition produced with a second prepolymer composition containing dispersed rubber particles.
