A series of new 3,3,3-trifluoropropyl substituted copoly(carbosiloxane)s have been prepared by Pt-catalyzed step-growth hydrosilylation copolymerization of 1,9-dihydrido-1,1,3,5,7,9,9-heptamethyl-3,5,7-tris(3′,3′, 3′-trifluoropropyl)pentasiloxane (I) with various α,ω-divinylsilanes and siloxanes. The structures of the copoly(carbosiloxane)s have been determined by 1H, 13C, 29Si, and 19F NMR as well as IR spectroscopy. The molecular weight distributions (Mw/Mn) of the copolymers have been characterized by GPC and their thermal properties measured by DSC and TGA. © 2002 Elsevier Science Ltd. All rights reserved.
