Abstract

Abstract Diphenyl (diphenylethynyl) silane ((ph–C≡ C) 2–Si–ph 2)(DPDPES) was synthesized by the Grignard reaction. The corresponding isothermal and non-isothermal cure kinetics of DPDPES were analyzed by using differential scanning calorimetry (DSC), and the molecular structure was characterized by H-NMR. The results showed that all the cure curves were typically sigmoid shape and cure reactions could be described by an ...
