POLYMERISABLE COMPOSITIONS FOR MAKING TRANSPARENT POLYMER SUBSTRATES, RESULTING POLYMER SUBSTRATES AND THEIR USES IN OPTICS

摘要

The invention concerns compositions comprising: (a) at least 40 parts by weight, preferably at least 50 parts by weight of at least a thio(meth)acrylate monomer; (b) at least a monomer with high Abbe coefficient; (c) not more than 20 parts by weight, preferably not more than 15 parts by weight, and advantageously not more than 10 parts by weight of an aromatic polyvinyl monomer; and (d) at least a polythiol; for 100 parts by weight of (a), (b), (c), and (d). The invention is useful for making optical lenses.
