Abstract
Homopolymerizations and copolymerizations of isopropyl perfluorooctylethyl fumarate (IPFOF) and isopropyl perfluorohexylethyl fumarate (IPFHF) were performed with radical initiators in bulk and in several solvents at 50°C to 150°C. The overall activation energy for the polymerization of IPFHF was 104.2 kJ mol−1. The reduced viscosities (ηsp/C) and glass transition points (Tg) for the polymers were 0.26 dl g−1 (in trifluoroacetic acid at 30°C) and about 42°C, respectively. The monomer reactivity ratios (r1, r2) in the copolymerizations of IPFOF (or IPFHF) with styrene or methyl methacrylate, and Alfrey-Price Q, e values were determined. Some of the copolymers contained about 10.0 dl g−1 of ηsp/C and about 70°C of Tg.
