[Also in Divisions C2 and C4] Polymeric materials are obtained by polymerizing unsaturated monomers of the Formula I: where n=1 and Ar is an acenaphthyl, fluorenyl, pyrenyl, phenanthryl or anthryl-2 radical or n= 2 and Ar is an acenaphthyl, fluorenyl, phenanthryl, anthryl, pyrenyl or naphthyl radical or by polymerizing monomers of Formula II: where Ar is a phenyl, naphthyl, anthryl, acenaphthyl, fluorenyl, phenanthryl or pyrenyl radical. |
