摘要：
The present invention relates to a process for preparing a hard transparent resin comprising polymerizing a monomer (A) having both a functional group of the following formula (I):
wherein X is selected from the group consisting of an oxygen atom and a sulfur atom,
and a functional group selected from the group consisting of a functional group of the formula (II): CH 2 CR-COO- (II) wherein R is selected from the group consisting of hydrogen and methyl group, and a functional group of the formula (III):
The invention also provides a process for preparing a transparent resin comprising copolymerizing monomer (A) with a monomer (B) having at least one functional group selected from the group consisting of CH 2 CH=COO-,
CH 2 = C(CH 3 )-COO-, and
This resin can be suitably used as a glazing material, and in the manufacture of optical lenses, optical information recording medium substrates, etc. It has a crosslinked structure, high surface hardness, and may be easily polymerized.
