A polymerizable composition for an optical material containing a polymerization reactive compound and a polyether-modified compound having a polyether group represented by general formula (4). (In general formula (4), R 25 represents a C1-20 linear or branched alkylene group, R 26 represents a hydrogen atom, a C1-20 linear or branched alkyl group, a C2-20 linear or branched alkenyl group or a C2-20 linear or branched alkynyl group. The plurality of R 25 which are present may be the same or different. k represents an integer of 1 or more.) |
