AROMATIC POLYESTER AND POLYESTER CARBONATE CONTAINING TERMINAL ARALKYLPHENYL GROUP AND PRODUCTION AND USE THEREOF

The novel aromatic, thermoplastic polyesters and polyester carbonates based on diphenols, dicarboxylic acids, chain terminators and optionally branching agents are characterised in that the chain terminators conform to the formula in which R1, R2 and R3 are identical or different and are C2- to C12-...

Beschreibung
Zusammenfassung:	The novel aromatic, thermoplastic polyesters and polyester carbonates based on diphenols, dicarboxylic acids, chain terminators and optionally branching agents are characterised in that the chain terminators conform to the formula in which R1, R2 and R3 are identical or different and are C2- to C12-alkyl or C8- to C20-aralkyl, and at least one of the radicals R1 and R2 is a C8- to C20-aralkyl radical and n has a value of from 0.5 to 1, and are suitable for the production of mouldings, films, fibres and filaments. The polyesters and polyester carbonates are distinguished by good thermal stability.
