ORGANOPOLYSILOXANE EMULSION AND FIBER TREATED WITH THE SAME EMULSION

摘要

PURPOSE:To produce an emulsion excellent in productivity and shelf life, free from an undesirable smell and useful as a treatment for fiber by conducting an emulsion polymerization of a specified diorganopolysiloxane and a specific alkoxy group-containing organosilicon compound in the presence of a surfactant in water. CONSTITUTION:This emulsion is produced by conducting an emulsion polymerization of (A) 100 pts.wt. diorganopolysiloxane represented by the formula R<2>O (R<1>2SiO)mR<2> [R<1> is a univalent organic group; R<2> is H or an alkyl; (m) >=10] and having 30 to 100000 centistokes at 25 deg.C and (B) 0.1 to 20 pts.wt. alkoxy group-containing organosilicon compound (e.g. a compound of formula II) of formula I (R<3> and R<4> are each a 1 to 8C univalent hydrocarbon; R<5> is an alkyl) in the presence of (C) 1 to 60 pts.wt. surfactant (a nonionic surfactant, an anionic surfactant and/or a cationic surfactant in combination) in water.
