A cyclic organosilicon endcapper having one aliphatic unsaturation |
摘要 |
<p>A cyclic organosilicon compound comprising one aliphatic unsaturation described by formula <CHEM> where each R is an independently selected hydrocarbon radical free from aliphatic unsaturation having 1 to 18 carbon atoms; each X is independently selected from halogen, alkoxy, acyloxy or ketoximo; m is an integer from 2 to 7; p is an integer from 0 to 6; m+p is an integer from 2 to 8; n is 0, 1 or 2; each Z is independently selected from divalent hydrocarbon radicals free of aliphatic unsaturation having 2 to 18 carbon atoms or a combination of divalent hydrocarbon radicals and siloxane segments; and Y is selected from hydrocarbon radicals comprising one aliphatic unsaturation and 2 to 18 carbon atoms or a combination comprising one aliphatic unsaturation of hydrocarbon radicals and siloxane segments. The cyclic organosilicon compounds comprising one aliphatic unsaturation of the present invention are useful as endcappers for polymers.</p> |
