Reversible addition fragmentation transfer (RAFT) belongs to the group of the controlled radical polymerization (CPR) methods, intensively employed in the synthesis of polymers with complex architectures and structures. 1,2 pHresponsive amphiphilic copolymers synthesized by RAFT, lead to materials with versatile properties. Optimization of the reaction kinetics during RAFT polymerization of 2-(dimethylamino)ethyl acrylate (DMAEA) in N,Ndimethylformamide (DMF) was investigated in this study, followed by the synthesis of DMAEA/styrene amphiphilic diblock copolymers, using Automatic Continuous Online Monitoring of Polymerization reactions (ACOMP). Poly(DMAEA) is a pH sensitive polymer with wide applications in pharmaceutical and water treatment industries yet challenging due to possible interaction of its amino group with catalysts.3,4
