Title:

BIS(CYCLIC CARBONATE), PRECURSOR THEREOF AND POLYCARBONATE COMPOSITION CONTAINING THE SAME

Document Type and Number:

Japanese Patent JPS6225123

Kind Code:

A

Abstract:

Novel bis(cyclic carbonates) are useful as crosslinking agents for polycarbonate compositions - (including cyclic polycarbonate oligomers), and, in combination with flame retardant agents, as anti-drip agents for polycarbonate resins. This bis(cyclic carbonates) may be prepared by the reaction of phosgene with novel tetraphenols, which in turn may be prepared by the condensation of aliphatic dialdehydes with phenols.
