摘要

Abstract

A carbosilane dendrimer based macrophotoinitiator(MPI-185)containing benzophenone moiety terminal groups was synthesized by a divergent bydrosilylation／allylation reaction sequence followed by alcoholysis of the silicon chloride end groups．The structure of MPI-185 was characterized by FTIR

1H-NMR

13C—NMR

and29Si—NMR

and its intrinsic viscosity

molecular weisht and polydispersity were meassured on by using a GPC complex system．Its reactivity was tested via curing a sensitive epoxy acrylate(EA)resin using FTIR

and the thermal preperty of films cured was measured by TGA．The results were compared with those of a small molecule photoinitiator(185)．It Was found that the cutting efficiency of macrophoinitiator(MPI-185)was satisfactory

and the thermal degradation temperature of EA resin eared with MPI-185 was also markedly improved．
