摘要：

The synthesis of new polysiloxanes bearing thioether and heterocyclic functions (epoxy or oxetane) was performed. The reaction is a radical addition between a poly(dimethyl - co-methyl mercaptopropyl) siloxane and allyl or vinyl heterocyclic compounds. The corresponding sulfones were obtained by oxidation of thioether functions by using,,m-chloroperbenzoic acid. All the products were characterized by H-1 NMR, SEC and viscosimetry. The cross-linking of these products with isophorone diamine was studied at different temperatures. Thermal and mechanical properties were examined by dynamical mechanical and thermogravimetric analysis. (C) 1998 Elsevier Science Ltd. All rights reserved.
