<p>The present invention disclosed improved copolycarbonates and methods for their synthesis that involve the incorporation of aliphatic diol carbonates into copolycarbonate chains under solid state polymerization conditions. More particularly, the present invention utilizes dipheny carbonate in the production of copolycarbonates that exhibit modified thermal properties(lower Tg) relative to analogous simple copolycarbonates. The solid sate polymerization technique possesses a distinct advantage over melt polymerization in that no specialized melt polymerization equipment is required.</p> |
