ACRYLOYL CHLORIDE POLYMER

Free radical polymerization of acryloyl chloride (AC) was conducted in the following solvents: dichloroethane, ethyl acetate, tetrahydrofura n, dichloromethane, dioxane, and cyclohexane. However, poly(acryloyl c hloride) with high molecular weights could be obtained only in solvent cyclohexane. The molecular weights of poly(acryloyl chloride) could b e measured through analogous poly(methyl acrylate). The reactivity rat ios of AC (M-1) with styrene (St) or vinyl acetate (VA) obtained by th e extended Kelen-Tudos method at 42 degrees C with dicyclohexylperoxyd icarbonate as initiator in dioxane were found to be AC-St (r(1) = 0.09 +/- 0.1, r(2) = 0.40 +/- 0.1) and AC-VA (r(1) = 0.84 +/- 0.1, r(2) = 0.03 +/- 0.1), respectively. The Q and e values of AC calculated from obtained r(1) and r(2) were 0.58 and 1.02. (C) 1998 John Wiley & Sons, Inc.
