POLYMERIZABLE COMPOUNDS AND USE THEREOF

摘要

[PROBLEMS] To provide polymerizable compounds useful as the raw material for resins which have high refractive indexes (nd) exceeding 1.7 as well as satisfy the requirements for optical members such as plastic lenses, e.g., high transparency, good heat resistance, and satisfactory mechanical strengths, and optical members made of the resin. [MEANS FOR SOLVING PROBLEMS] Compounds represented by the general formula (3) wherein M is a metal atom; X1 and X2 are each independently sulfur or oxygen; R1 is a divalent organic group; m is an integer of 0 or above; p is an integer of 1 to n; q is an integer of 1 to (n-p); n is the valence of M; and Yq's are each independently an organic or inorganic group; with the proviso that when q is 2 or above, Yq's may be bonded to each other to form a cyclic structure together with M.
