Patent ID: 8110710

Claim:
A process for producing bisalkoxylated diols of bisphenol A which comprises the steps of: (a) digesting polycarbonate (PC) or PC waste with alkylene glycol in the presence of a basic catalyst at a temperature of about 100° C. to about 250° C. under normal atmospheric pressure; and (b) forming bisalkoxylated diols of bisphenol A by adding chemical A to the digested product of step (a) in the presence of a metal oxide catalyst at a temperature of about 100° C. to about 250° C. under normal atmospheric pressure, wherein chemical A represents an amine ester having the following formula (III): wherein R 11 and R 12 each independently represents H or C 1 -C 6 alkyl, and R 13 represents C 1 -C 6 alkyl.
