POLYIMIDE FILM WITH IMPROVED DIELECTRIC PROPERTIES AND MANUFACTURING METHOD THEREOF

摘要

The present invention is an imidation reaction of a dianhydride component containing benzophenonetetracarboxylic dianhydride (BTDA) and biphenyltetracarboxylic dianhydride (BPDA) and a diamine component containing paraphenylene diamine (PPD) a first block obtained by and a dianhydride component including biphenyltetracarboxylic dianhydride (BPDA) and pyromellitic dianhydride (PMDA) and a diamine component including m-tolidine. Provided is a polyimide film with improved dielectric properties, including a block copolymer including a second block.
