polybutylenterephthalat, mixtures of this polybutylenterephthalat and aromatic polycarbonate, and from these materials manufactured goods

摘要

The invention relates to polybutylene terephthalates having a content of terminal COOH groups of less than 30 meq/kg and a number-averaged molecular weight of at least 30,000 and to polymer mixtures comprising such a polybutylene terephthalate. The polybutylene terephthalate according to the invention and the polymer mixtures comprising the said polybutylene terephthalate have a good lacquer bonding.
