Title:
THIOEPOXY BASED POLYMERIZABLE COMPOSITION AND METHOD FOR PRODUCTION THEREOF
Document Type and Number:
WIPO Patent Application WO/2003/076496
Kind Code:
A1
Abstract:
A polymerizable composition containing a compound having at least one moiety represented by the formula (1): (1) wherein R1 represents a hydrocarbon group having 1 to 10 carbons, and each of R2, R3 and R4 represents a hydrocarbon group having 1 to 10 carbons or a hydrogen atom, characterized in that it contains a thioepoxy compound (A) having at least one moiety represented by the formula (2): (2) and at least one moiety represented by the formula (3): (3), and a thioepoxy compound (B) having at least one moiety represented by the formula (4): (4) and at least one moiety represented by the formula (3), in a sum of the amounts of both compounds of 4 mass % or less relative to the total amount of the polymerizable composition; and a method for producing the polymerizable composition. The use of the polymerizable composition allows the suppression of the reduction in yield due to variations or irregularities in refractive index, color, optical strain, or the like.
