Abstract
Abstract Polycarbonate and polyarylate resins are chain-terminated with a group selected from those of the formula: ##STR1## wherein each R independently represents one of hydrogen or lower alkyl. The resins are reactive polycarbonates, poly(ester carbonates) and polyarylates, useful as intermediates in the preparation of block and graft copolymers, with other polymers having functional, reactive groups.
