Photorefraction Fullerene-Containing Polymer, Producing Method Thereof, and Photorefractive Composition

Title Fullerene-Containing Polymer, Producing Method Thereof, and Photorefractive Composition 

A composition comprising a Ceo fullerene-terminated poly(A-[(propylphenyl]-AA, A -triphenyl-(l,l - biphenyl)-4,4 -diamine)methacrylate has been prepared by living radical polymerization. When blended with a plasticizer and a nonlinear chromophore, photorefractive efficiencies were improved by up to 9% at abiased voltage of 60 V/pm. 

Preparation of Poly(A-[(Propylphenyl]-N,N, A -Triphenyl-(1,1 -Biphenyl) -4,4 -Diamine)Methacrylate 

The charge transport agent, N- [(meth)acroyloxypropylphenyl] A -triphenyl-) 1,1 - 

The mixture was then diluted with toluene and filtered to remove insoluble impurities. The polymer was precipitated from the solution by adding methanol, filtering, and washing with diethyl ether and methanol to remove unreacted acrylate monomer. The product was dried, and the product isolated had a M of 8317 daltons.
