ABSTRACT:
Polycarbonates (PC) can be blended over all compositions with block copolymers containing polyaromatic(alkyl)methacrylates (PAAM) to form modified but transparent polycarbonates for a number of applications. Furthermore, additional homopolymers corresponding to those in the block copolymer may also be added to further modify the properties of the polycarbonate while still retaining transparency. Polycarbonate plus PAAM block copolymers containing from 1 to 99% by weight PC behave as transparent materials with the PC and the PAAM block forming a continuous, single phase material.
