ABSTRACT:
A silicon-phthalocyanine-siloxane polymer having the formula ##STR1## WHEREIN Pc is a phthalocyanine nucleus, Ph is a phenyl group, n is an integer from 1 to 8, and x is an average value up to 20, is prepared by a method including a reaction of a phthalocyanine-silicon-disilanol with a bis(ureido) dialkyl silane or bis(ureido) siloxane or by the reaction of a phthalocyanine-silicon-disilanol with a bis(dialkyl) amino) silane or a bis(dialkylamino) siloxane. These polymers are useful as strengthening agents for high-temperature resins, such as polyimides, poly(phthalocyanines) or epoxies and as coatings or dyes.
