ABSTRACT:
A cyclic organosilicon compound comprising one silicon-bonded hydrogen atom described by formula ##STR1## where each R is an independently selected hydrocarbon radical free from aliphatic unsaturation comprising 1 to about 18 carbon atoms; each X is independently selected from the group consisting of halogen, alkoxy, acyloxy, and 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; and each Z is independently selected from the group consisting of divalent hydrocarbon radicals free of aliphatic unsaturation comprising about 2 to 18 carbon atoms and a combination of divalent hydrocarbon radicals and siloxane segments. The cyclic organosilicon compounds comprising one silicon-bonded hydrogen atom of the present invention are useful as endcappers for polymers.
