Synthesis and Post‐Polymerization Modification of Poly( <i>N</i> ‐(4‐Vinylphenyl)Sulfonamide)s

Herein, a straightforward synthesis of novel class polymers, that is, poly(N-(4-vinylphenyl)sulfonamide)s, and their monomers is reported. A set with varying electron densities, fine-tuned by different substituents on the aromatic sulfonamide moiety, polymerized free radical polymerization featuring low molar masses (2300 ≤ Mn 3200 g mol−1) dispersities (1.15 Đ 1.47). Further, post-polymerization modification obtained polymers via aza-Michael addition electron-deficient alkenes demonstrated using organic superbases as catalysts, paving way toward facile polymeric protected β-amino acid derivatives.
