This article describes the preparation of a kind of auto-photosensitive polyimide (PSPI) that contains organo-silicone moiety in its main chain. A group of novel auto-photosensitive polyimides were prepared based on the aromatic diamine monomers and 3,3',5,5'-benzophenontetracarboxylic dianhydride (BTDA) by the method of solution polycondensation at room temperature and imidized at a high temperature. The properties of PSPIs, such as ultraviolet (UV) absorption, electric and adhesion properties, and moisture absorption, were characterized by UV analysis, a dielectric constant detector, and so on. The relationship between the structure and properties of PSPIs is discussed. (C) 2000 John Wiley & Sons, Inc.
