Abstract
A process for crosslinking a polycarbonate resin involves heating the polycarbonate resin in the presence of an organic copper compound at a temperature higher than the glass transition point of the polycarbonate resin.
Claims20
A process for crosslinking a polycarbonate resin comprising heating a mixture comprising (1) a polycarbonate resin selected from the group consisting of (i) polycarbonate obtained (a) by the dehydrochlorination of a dihydroxyphenyl alkane with phosgene, or (b) by an ester interchange of a dihydroxyphenyl alkane with diphenyl carbonate, and (ii) a polymer composition containing said polycarbonate as a major component thereof, at a temperature higher than the glass transition point of said polycarbonate resin and (2) an organic copper compound which is compatible with said polycarbonate resin, the amount of said organic copper compound being sufficient to catalyze the crosslinking of said polycarbonate resin.
