| 摘要 |
A silicone oil-in-water emulsion containing a linear noncrosslinked silicone copolymer is prepared by polymerizing an OH endblocked polydimethylsiloxane monomer with an amine functional trialkoxysilane monomer in the presence of a metal catalyst. However, the polymerization is interrupted by the emulsification of this copolymer, and a carboxylic anhydride is added prior to the emulsification. The resulting emulsions are particularly useful in most personal care applications, and they also have value in textile fiber treatment, leather lubrication, fabric softening, as release agents, in water based coatings, for oil drag reduction, lubrication, and for the facilitation of cutting of cellulose materials.
