| abstract | PCT No. PCT/JP89/00345 Sec. 371 Date Nov. 8, 1989 Sec. 102(e) Date Nov. 8, 1989 PCT Filed Mar. 31, 1989 PCT Pub. No. WO89/09418 PCT Pub. Date Oct. 5, 1989.The plastic lens of the present invention consists of a copolymer obtained by copolymerizing a monomer mixture consisting of given proportions of diethylene glycol bis(allyl carbonate), benzyl methacrylate, diallyl phthalate (these three monomers has been used as a monomer mixture for conventional plastic lenses) and, as an additional monomer, an alkyl methacrylate. This copolymer has excellent adhesion to upper and lower molds and, when immersed in, for example, a cleaning solution such as a methylene chloride-strong alkali mixed cleaning solution or the like, causes no separation from the molds; accordingly in the copolymer, there can be prevented the occurrence of surface roughening, cloudiness and striae which have been problems in conventional plastic lenses. |
