Paragraph 0082, (2019/09/21)
PROBLEM TO BE SOLVED: To provide a new monomer compound from which an optical material can be manufactured that has at least one improved characteristic in a high refractive index and a high glass transition temperature, and a composition for an optical material comprising the above compound. SOLUTION: The present invention discloses a polyfunctional propargyl compound represented by formula (1) below. In the formula, m represents an integer of 3 to 30; R1 represents an alkyl which may have one or more sulfide bonds in the chain, and the alkyl is substituted if necessary; and each RA is independently selected from the group consisting of a hydrogen atom, halogen, alkyl having 1 to 10 carbon atoms, substituted or unsubstituted phenyl, substituted or unsubstituted naphthyl, and silyl.
