Aromatic polyester polycarbonates from polyols derived from recycled polyethylene terephthalate

Ernest L. Yeakey; Michael Cuscurida

A novel class of aromatic polyester polycarbonates is described. The polycarbonates are made by reacting an alkylene carbonate with an aromatic polyester polyol over a polycarbonate formation catalyst such as potassium stannate. In turn, the polyol is made by esterifying a dibasic acid waste stream with an alkylene glycol to produce a polyester polyol which is subsequently used to transesterify recycled polyethylene terephthalate.
