Abstract

Tough transparent thermoplastics blends may be prepared by blending 10 to 99 weight percent of a block copolymer; 0.1 to 1 weight percent of particulate rubber having a particle size from 0.1 to 10 microns; and the balance a clear glassy polymer. These clear polymers are useful in a number of applications, particularly for those applications requiring quite high toughness and transparency such as packaging, containers or protective covering.
