EPOXY ACRYL BASED POLYMERIZABLE COMPOSITION AND METHOD OF PREPARING EPOXY ACRYL BASED OPTICAL MATERIAL

摘要

The present invention relates to an epoxy acryl-based polymerizable composition for an optical material and a manufacturing method for an epoxy acryl-based optical material and more specifically, to a manufacturing method for an epoxy acryl-based polymerizable composition for an optical material which is easily manufactured into an optical material by maintaining proper viscosity and reaction ratio, and an optical material. The present invention provides an epoxy acryl-based compound and the epoxy acryl-based polymerizable composition for an optical material including a dibenzylmalate product containing 10-25 wt% of monobenzylmalate. The present invention is able to provide the epoxy acryl-based polymerizable composition for an optical material with proper handling properties and reactivity which is useful for the manufacture of an optical material by using the dibenzylmalate product containing 10-25 wt% of monobenzylmalate with monomer components. The present invention is able to manufacture the polymerizable composition which has high abbe number while having high refractive index and exhibits excellent optical properties such as transparency, lightness, heat resistance and the like by polymerizing the polymerizable composition of the present invention.
