Abstract
A polymerizable composition that includes a monomer of the formula wherein X is hydrogen or one or more of methyl, chlorine, bromine or iodine, R1 is a straight or branched alkyl linking group of 2 to 12 carbon atoms, R2 is hydrogen or methyl, and n is 1 to 3; and a monomer of the formula wherein X1 and X2 are each independently hydrogen or one or more of methyl, chlorine, bromine or iodine, and R2 is hydrogen or methyl is described having a high index of refraction and being suitable for use in forming an optical product.
