ABSTRACT:
A polyester sheet containing an antiblock agent is produced by uniformly blending a small amount of a degraded polycarbonate containing the antiblock agent. The antiblock agent must have an inherent or adjusted pH of less than six to degrade the polycarbonate to lower its molecular weight upon extrusion compounding. This in turn makes a uniform blend and resulting clear sheet with antiblocking properties. In another embodiment, larger amounts of polycarbonate containing the antiblock agent are used.
