Title:
POLYIMIDE COMPOSITIONS
Document Type and Number:
WIPO Patent Application WO/1999/051662
Kind Code:
A1
Abstract:
Novel polyimide compositions having a cinnamic acid or cinnamic acid derivative skeleton and possessing both the photoreactivity and heat reactivity characteristic to the cinnamic acid skeleton. Novel diamines and acid dianhydrides, which are usable mainly in producing the above novel polyimide compositions having the cinnamic acid skeleton, having the cinnamic acid skeleton or the cinnamic acid derivative skeleton in the main chain or in the side chain.
