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.
