摘要: The present invention relates to a method for manufacturing wholly aromatic polyimide resin having good mechanical properties and improved heat resistance, more particularly, that has resistance elongation tenacity in high temperature range, wherein the comprises: solution polymerization of two types tetracarboxylic acid dianhydride are controlled proportion, diamine. While retaining virtually all characteristics polyimide, manufactured according such it can be applied as an important material semiconductor industry aerospace field, which require higher levels excellent properties.
