Abstract:

In this study, poly(ε-kaprolactone)-b-poli(acrylamide) bloc copolymers were synthesized through one step by reverse-related/related chain transfer (RAFT) and open-power polymerization methods. For this, the two-handed RAFT-ROP trigger was synthesized by the two-functional 2-(2-chlorine ethoxy) ethanol trigger, which enables both the polymerization of the opening and the reverse participating/related chain transfer polymerization at the same time and in a single step. This obtained RAFT-ROP starter used poly(CL-b-AAm) block copolymers were synthesized by changing the monomer quantity. Block copolymers block lengths were calculated with the help of 1H-NMR. The bloc lengths of the synthesized bloc copolymers can be adjusted by the change of the monomer concentration. Block copolymers were characterized using 1H-NMR, FT-IR, DSC and SEM techniques.

Abstract:

In this study, poly(acrylamide–b–ԑ-caprolactone) block copolymers were synthesized by a combination of reversible addition-fragmentation chain transfer (RAFT) polymerization and ring-opening polymerization (ROP) methods using a chain-transfer agent (RAFT-ROP initiator) which was obtained via the reaction of 2-(2-Chloroethoxy)ethanol with the potassium salt of ethyl xanthogenate. The block length of the block copolymers could be adjusted by changing monomer concentrations. The characterization of the products was achieved using 1H-NMR, FT-IR, DSC and SEM techniques.
