| Abstract: | A study has been carried out on the preparation of some modified imide-siloxane copolymers. This has been accomplished by means of addition of α,ω-dihydropoly(di-methylsiloxane)s to N,N'-diallyldiimides by hydrosilylation reaction. The copolymers were characterized by IR and NMR spectroscopy methods. Molar mass, molar mass distribution, thermal and mechanical properties of copolymers were determined. These copolymers are used as additives, mixing them in different ratios with a silicone polymer and filler to obtain imide-silicone rubbers of high temperature vulcanizing (HTV) type. Mechanical properties of the vulcanized rubbers were evaluated. |
