PRODUCTION OF LIQUID CRYSTAL POLYMER FILM

摘要

PURPOSE:To obtain the subject film free from wrinkle and having improved thermal properties by reheating and melting a film of a thermotropic liquid crystal polyester at a specific temperature and heat-setting the treated film. CONSTITUTION:The objective film can be produced by reheating and melting a film of a thermotropic liquid crystal polyester at a temperature between the melting temperature and the cooling crystallization temperature and heat- setting the treated film.
