Abstract
A poly(siloxane-diphenylbutadiyne) exhibiting thermosetting properties, a highly tunable glass transition temperature (Tg), and very high thermal and thermo-oxidative stability. In one embodiment, the poly(siloxane-diphenylbutadiyne) is a poly(tetrasiloxane-diphenylbutadiyne). The present subject matter also relates to a method of synthesizing the poly(tetrasiloxane-diphenylbutadiyne).
