The present invention is a polyether-modified siloxane represented by average composition formula (1) of (R 3 SiO 1/2 ) a (R 2 R'SiO 1/2 ) a' (R 2 SiO 2/2 ) b (RR'SiO 2/2 ) b' (RSiO 3/2 ) c (SiO 4/2 ) d . In formula (1), R is a hydrogen atom, a hydroxyl group, a monovalent hydrocarbon group having 1-18 carbon atoms, or an alkoxy group having 1-10 carbon atoms, R' is an organic group selected from groups represented by -C q H 2q -O-(C 2 H 4 O) e (C 3 H 6 O) f -R 1 , R 1 is a hydrogen atom, a hydrocarbon group having 1-30 carbon atoms, or an organic group represented by R 6 -(CO)-, and R 6 is a hydrocarbon group having 1-30 carbon atoms. Consequently, it is possible to provide a novel polyether-modified siloxane which has a low environmental load and imparts excellent antifouling performance. |
