Synthesis of a novel type of octyltetramethyldisiloxane-containing olefinic macromonomer and its copolymerization with ethylene

This paper reported the synthesis of a novel type of octyltetramethyldisiloxane-containing olefinic macromonomer (1-oct(7-en)yl-3-octyl-1,1,3,3-tetramethyldisiloxane or OO7), the copolymerization of OO7 with ethylene by vanadium catalyst, the evaluation of poly(ethylene-co-OO7) as additive on the flow, mechanical and thermal properties of polyethylene. The novel siloxane-containing comonomer OO7 was synthesized by a two-step hydrosilylation …
