    摘要: A method of making siloxane-based polyamides which includes at least one repeating unit represented by the formula wherein X is a linear or branched C1-C30 alkylene chain; Y is a linear or branched C1-C20 alkylene chain; DP is an integer having a value of 10-500; n is an integer having a value 1-500. The method involves heating an intimate reaction mixture containing an olefinic acid and an organic diamine at a temperature greater than 100° C. and forming an organic diamide; and thereafter reacting the organic diamide with a hydride-terminated polydimethylsiloxane in the presence of a hydrosilylation catalyst to form the siloxane-based polyamide.

    摘要: A method of making siloxane-based polyamides which includes at least one repeating unit represented by the formula ##STR1## wherein X is a linear or branched C.sub.1 -C.sub.30 alkylene chain; Y is a linear or branched C.sub.1 -C.sub.20 alkylene chain; DP is an integer having a value of 10-500; n is an integer having a value of 1-500. The method involves heating an intimate reaction mixture containing an olefinic acid and an organic diamine at a temperature greater than 100.degree. C. and forming an organic diamide; and thereafter reacting the organic diamide with a hydride-terminated polydimethylsiloxane in the presence of a hydrosilylation catalyst to form the siloxane-based polyamide.
