Branched, high-molecular weight thermoplastic polycarbonates
摘要:
The invention relates to a process for the preparation of branched, thermoplastic, high-molecular weight and soluble polycarbonates having improved properties, by incorporation of 3,3-bis-(4-hydroxyaryl)-oxindoles as a branching agent. The invention further relates to the polycarbonates obtained in accordance with this process.
