Abstract
A polyether-modified siloxane represented by an average composition formula (1): (RSiO)(RR'SiO)(RSiO)(RR′SiO)(RSiO)(SiO). In the formula (1), 'R's each represent a hydrogen atom, a hydroxy group, a monovalent hydrocarbon group having 1 to 18 carbon atoms, or an alkoxy group having 1 to 10 carbon atoms, “R”'s each represent an organic group selected from groups represented by —CH—O—(CHO)(CHO)—R, Rs each represent a hydrogen atom, a hydrocarbon group having 1 to 30 carbon atoms, or an organic group represented by R—(CO)—, and Rrepresents a hydrocarbon group having 1 to 30 carbon atoms. This can provide a novel polyether-modified siloxane that has little environmental impact and that provides excellent antifouling performance.
