    摘要: Disclosed herein are a resin for high-refractivity lenses, formed by copolymerizing at least one nucleus-halogenated benzene dicarboxylate represented by the following general formula (I): ##STR1## wherein X means a chlorine or bromine atom, n is 2 or 4, m stands for 0 or 1 and R denotes a hydrogen atom or a methyl group with at least one unifunctional monomer having a refractive index of at least 1.55 as a homopolymer, capable of undergoing a radical polymerization and containing an aromatic ring as well as high-refractivity lenses made of such a resin. The lens-making resin according to this invention features a high refractive index, excellent processability such as superb grinding processability and high impact resistance, outstanding miscibility between the unifunctional monomer and bifunctional monomer upon copolymerization thereof, and minimized polymerization strain.

    摘要: A compatible, gellable, dual resin system useful for impregnating porous spacers between stator end windings of turbine generators is made from (A) a liquid diallyl isophthalate component comprising an admixture of liquid diallyl isophthalate monomer and solid diallyl isophthalate prepolymer, where the weight ratio of monomer:prepolymer is between about 1.5:1 and about 3.0:1, (B) an amount of chain forming isocyanate terminated polyurethane prepolymer effective to provide a chain network which physically interpenetrates the liquid diallyl isophthalate component, and prevents free flow of liquid diallyl isophthalate component, (C) a chain extender for the isocyanate terminated polyurethane prepolymer, and (D) a catalyst for the diallyl isophthalate component, where the resin system is curable with the application of heat.
