PURPOSE: To obtain an inorg.-org. composite polymer compsn. with excellent transparency and homogeneity by compositing a general-purpose org. polymer with an inorg. polymer.
CONSTITUTION: An org.-inorg. composite polymer compsn. wherein an org. component is composited with an inorg. component is obtd. by hydrolysis- polymerizing an organometallic compd. with a hydrolysis-polymerizable org. group in the presence of polyoxazoline and/or polyvinylpyrrolidone and an org. polymer. The org. polymer includes a polymer with a polar group such as a halogen atom, an oxygen atom or a nitrogen atom. The organometallic compd. includes an org. silicon compd. such as tetramethoxysilane. 1-3,000 pts.wt. org. polymer and 25-5,000 pts.wt. (in terms of organometallic compd.) organometallic polymer are incorpporated in 100 pts.wt. polyoxazoline or polyvinylpyrrolidone in the compsn.
