Abstract Poly(acrylic acid) (PAA) is a hydrophilic polymer widely utilized in various everyday applications, but it may persist the environment due to its stable carbon‐carbon (C‐C) backbone. This work presents detailed comparative study of introducing hydrolyzable ester breaking points into PAA backbone using different radical copolymerization methods (bulk versus solvent and batch semi‐batch) with varied feed ratios tert ‐butyl acrylate (tBA) 2‐methylene‐1,3‐dioxepane (MDO) followed by investigation removal t ‐Bu group for getting free acid functionality copolymers under conditions. A comparison polymerization approaches solution, revealed that solution at 100 °C peroxide provided high ring‐opening efficiency (71%) uniform molecular weight distribution. The optimized deprotection processes tBA acrylic acid, achieving complete hydrolysis mild conditions 5 equivalents trifluoroacetic dichloromethane. resultant polymers displayed pH temperature dependent solubility significant degradation alkaline conditions, formation oligomers (400–700 Da 35% MDO content) suitable microbial assimilation. These findings highlight scalable pathway creating environmentally degradable alternatives tailored properties functional applications.
