Copoly (carbonate/phosphonate) compositions |
摘要 |
Improved copoly(carbonate/phosphonate) compositions formed by reaction of a dihydric phenol, a carbonate precursor, and an organophosphorus dihalide are disclosed. The inherent viscosity and melting point of such compositions is increased by the presence of an effective amount of a chain branching agent, optionally in the additional presence of a chain terminating agent.
