THIOEPOXY-BASED POLYMERIZABLE COMPOSITION

Title:

THIOEPOXY-BASED POLYMERIZABLE COMPOSITION

Document Type and Number:

Japanese Patent JP2007327060

Kind Code:

A

Abstract:

To provide a polymerizable composition giving a resin composed of a thioepoxy-based compound and having decreased variations of refractive index, hue, optical distortion, etc., and provide a method for the production of the composition.

The polymerizable composition contains a compound having one or more structures expressed by formula (1) (R1is a 1-10C hydrocarbon group; and R2, R3and R4are each a 1-10C hydrocarbon group or hydrogen atom) provided that the total amount of the thioepoxy compound A having at least one dithioepoxy structure and at least one thioepoxy structure and the thioepoxy compound B having at least one epoxy structure and at least one structure expressed by thioepoxy is ≤4 mass% based on the total mass of the polymerizable composition.
