Alternating copolymers of styrene with β‐carboalkoxy‐substituted t‐butyl α‐cyanoacrylates undergo facile deesterification at 150–190°C, about 60°C below the deprotection temperature of poly(t‐butyl methacrylate), and decarboxylation at 170–200°C. When the β‐substituent is a methyl ester, the two events are clearly separated, with the deesterification occurring at a maximum rate at 165°C and decarboxylation at 193°C. Anhydride formation is negligible in this case. The copolymer with t‐butyl cyanofumarate exhibits simultaneous deesterification and decarboxylation events at 180°C with concomitant minor dehydration.
