Copolymerization behavior of m‐ and p‐styrenesulfonyl fluorides

Styrenesulfonyl fluorides are useful starting materials for the synthesis of a broad range of polymers and copolymers of styrenesulfonic acid. The reactivity ratios were determined for the copolymerization of m‐ and p‐styrenesulfonyl fluoride with styrene and with methyl acrylate: r1 r2 styrene/m‐styrene‐SO2F ..... 0.80 1.25 styrene/p‐styrene‐SO2F ..... 0.25 1.30 methyl acrylate/m‐styrene‐SO2F ..... 0.14 1.50 methyl acrylate/p‐styrene‐SO2F ..... 0.20 4.0 From these experimental results, the resonance and electrical factors were calculated Q e m‐styrene‐SO2F ..... 1.3 −0.7 p‐styrene‐SO2F ..... 1.6 +0.2
