ABSTRACT:
Siloxane-based polyamide elastomers can be prepared by heating a reaction mixture containing an olefinic acid and an organic amine to form an organic amide, and reacting the organic amide with a hydride functional polyorganosiloxane in the presence of a hydrosilylation catalyst to form the siloxane-based polyamide elastomer. The hydride functional polyorganosiloxane contains at least one pendant hydrogen. The elastomers are useful additives in personal care products and can be applied to the hair, the skin, or the underarm. They can also be used to modify thermoplastic nylons, and for treating woven and non-woven textiles, such as air bags, carpeting, and apparel.
