質塩化ビニル樹脂等が使用されていた。 Plastic lenses are mainly used as eyeglass lenses because they are lightweight and have excellent impact resistance and stainability. This plastic lens is usually manufactured by injecting a liquid monomer such as diethylene glycol bisallyl carbonate between glass molds, polymerizing and curing it in a heating furnace, and then removing the mold.
In order to maintain this glass mold at appropriate intervals and to prevent liquid monomer from leaking,
A plastic gasket is used. This gasket requires appropriate flexibility for mold assembly and removal, and also requires good thermal stability since it will be maintained at high temperatures for long periods of time. Conventionally, ethylene-vinyl acetate copolymers, ethylene-ethyl acrylate copolymers, soft vinyl chloride resins, and the like have been used as gasket materials that satisfy such required performance.

ンズの周辺が白濁してしまうからである。 However, although these resins conventionally used as gasket materials can be used with monomers such as diethylene glycol bisallyl carbonate, they cannot be used with monomers having aromatic rings. This is because monomers having aromatic rings have a large dissolving power for resins and dissolve a portion of the gasket during cast polymerization, resulting in cloudy surroundings of the resulting lens.
本発明の目的は、樹脂溶解性の高い液状モノマ
