Patent ID: 7833820

Claim:
A method for producing a polymer composition for semiconductor optoelectronics, comprising the steps of providing a monomer having the formula: (R 1 ) x Si(R 2 ) y or Ia (R 1 ) x Si—R 3 —Si(R 2 ) y IIa wherein: R 1 is a hydrolysable group R 2 is a phenanthrene or anthracene group, R 3 is an optional bridging linear or branched bivalent hydrocarbyl group, and x and y are integers from 1 to 3, homo- or copolymerizing the monomer to produce a polymer or copolymer, and combining 100 parts by weight of the polymer or copolymer with 1 to 500 parts by weight of nanoparticles selected from the group consisting of metals, metal alloys, metal oxides, carbides and nitrides and mixtures thereof to provide a nanoparticle containing polymer composition.
