Abstract

3,3,3‐Trifluoropropene, 4,4,4‐trifluorobutene‐1, 5,5,5‐trifluoropentene‐1, 3‐trifluoromethylbutene‐1, and 4‐trifluoromethylpentene‐1 were prepared and subjected to polymerization conditions with a variety of heterogeneous catalysts. The latter four monomers were polymerized to crystalline, high melting solids by means of vanadium trichloride–triisobuty aluminum catalyst. Infrared analysis indicates that there was no isomerization of the polymer chain.

The novel monomer, p-vinylphenoxy(trimethyl)silane, has been prepared and copolymerized with styrene. The hydrolysis of the copolymer in dioxan has been examined briefly. Monomers of the type p-CH.,~--CHC6H+SiMe2R (R = H, OMe, OEt, OPr', CH2CI and NMe2) have been prepared, polymerized and the result
