Thermoset Polymers Made by Blending Poly (Carborane-Siloxane/Silane-Acetylene) and Poly (Siloxane/Silane-Acetylene).
Abstract
An organoboron thermoset polymer precursor composition is made up of a mixture of a first linear polymer having a repeating unit comprising at least one carboranyl group, at least one silyl or siloxyl groups, and at least one acetylenic group, and a second linear polymer having a repeating unit comprising at least one silyl or siloxyl groups and at least one acetylenic moiety and wherein the second linear polymer does not contain a carboranyl group. The amount of carborane in the thermoset can be controlled by varying the relative amount of the carborane-containing polymer and the non-carborane-containing polymer in the precursor composition. The organoboron thermoset polymer precursor is used to make a thermoset by curing the precursor composition with heat or light, and to make a ceramic by pyrolyzing the precursor composition or a thermoset made from the precursor composition.
