SYNTHETIC RESIN LENS AND PROCESS FOR PRODUCING THE SAME |
摘要 |
<p>Disclosed is a plastic lens formed of a crosslinked polymer obtained by polymerizing or copolymerizing a monomer composition comprising as essential component the following component (A) and/or the following component (B), and optionally a component (C) composed of at least one monomer copolymerizable with the essential component comprising the component (A) and/or the component (B): Component (A): an ester obtained from (1)(a) a diol which is obtained by reducing a dimer of an unsaturated fatty acid having 16-18 carbon atoms and/or (b) a diol which is obtained by reducing a dimer of a lower alcohol ester of an unsaturated fatty acid having 16-18 carbon atoms, and (2) acrylic acid or methacrylic acid; and Component (B): an ester obtained from (1)(a) a triol which is obtained by reducing a trimer of an unsaturated fatty acid having 16-18 carbon atoms and/or (b) a triol which is obtained by reducing a trimer of a lower alcohol ester of an unsaturated fatty acid having 16-18 carbon atoms, and (2) acrylic acid or methacrylic acid. The plastic lens is high in density of crosslinking and low in specific gravity and has good optical properties.</p> |
