ABSTRACT:
Polycarbonates (PC) can be blended over all compositions with block copolymers containing stereoregular polymethyl methacrylate (s-PMMA) in which at least 60% of the monomer units are in the syndiotactic configuration to form modified but transparent polycarbonates for a number of applications. Additional homopolymers corresponding to the blocks of the copolymer may also be added to even further modify the properties of the polycarbonate while still retaining transparency.
