    摘要: 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.

    摘要: A method for preparing ceramic material from a polymer which comprises selecting a polymer from the class consisting of poly(diorganosilanes), poly(haloorganosilanes), poly(carbosilanes), polysilazanes, polycarbocarboranes, and polyborazines; heating said polymer to a temperature from 700.degree. to 2000.degree. C at a rate of at most 100.degree. C/hr. in an inert atmosphere for at least one hour; and cooling to room temperature at a cooling rate which avoids thermal stresses.
