Problems solved by technology

However, even in the case of using a reactive diluent, it is difficult to stably maintain a constant polymerization rate
In the case where an appropriate polymerization rate cannot be maintained, that is, when the reaction rate is slow at the beginning but suddenly becomes faster as the temperature rises, pulses, whitening, etc. may occur. On the contrary, when the polymerization proceeds too much after mixing In the case of fast, due to incomplete polymerization, various optical properties such as refractive index, strength, and transparency are lowered, and the quality of the finally obtained lens is lowered. As a result, the yield of the lens is lowered.

Embodiment 1

[0072] Add 0.5 g of α-methylstyrene as a polymerization regulator to 15 g of component (I), 30 g of component (III) and 10 g of component (V) in the epoxy acrylate compound obtained as above Dipolymer, 40g of styrene and 5g of α-methylstyrene as a reaction diluent, and add 2g of diphenyl dodecyl phosphate (DPDP, diphenyl dodecyl phosphate) as a heat stabilizer, 1g Dioctanoic acid phosphate (DOP, dioctylacid phosphate) and 1 g of triphenyl phosphite (TPP, triphenyl phosphite) were stirred for about 30 minutes. Afterwards, filter with a filter paper of 0.45 μm or less, add 0.05 g of V65, 0.12 g of 3-M as a catalyst, and add 0.05 g of 4-PENPP and 0.2 g of 8-M as an internal release agent. PENPP and mixed to prepare a polymerizable composition. The thus-prepared polymerizable composition for an optical lens was stirred for 1 hour, degassed under reduced pressure for 10 minutes, filtered, and then poured into a glass mold assembled with a polyester adhesive tape. The glass mold i...

Abstract

The present invention relates to a polymerizable composition for an epoxy-acrylic optical material and a method for producing an epoxy-acrylic optical material. In particular, it relates to maintaining an appropriate polymerization rate so that a high-quality product without veining or whitening can be obtained at a high yield. A polymerizable composition for an epoxy acrylic optical material and a method for preparing the optical material. The present invention provides a polymerizable composition for epoxy acrylic optical materials, which contains epoxy acrylate compounds, and the above polymerizable composition for epoxy acrylic optical materials contains 0.1 to 2 weight percent of α ‑Methylstyrene dimer. In the present invention, by stably maintaining an appropriate polymerization rate, a high-quality epoxy-acrylic optical material free from veins, whitening, and the like can be easily produced at low production costs.

Description

technical field [0001] The present invention relates to a polymerizable composition for an epoxy-acrylic optical material and a method for producing an epoxy-acrylic optical material, and particularly relates to maintaining an appropriate polymerization rate so that a high-quality product without veining or whitening can be obtained at a high yield A polymerizable composition for an epoxy acrylic optical material and a method for preparing the optical material. Background technique [0002] Plastic optical lenses are introduced as high specific gravity and low impact alternatives to solve the problems of glass lenses. Representative examples include polyethylene glycol bis (allyl carbonate), polymethyl methacrylate, diallyl phthalate, and the like. However, optical lenses prepared from polymers among them are excellent in physical properties such as templating properties, dyeability, hard coating film tightness, and impact resistance, but there are problems due to the refra...
