New block copolymers were synthesized from n-butyl acrylate (n-BA) and p-dodecylphenyl-N-acrylamide (DPAA) by reversible addition-fragmentation chain transfer (RAFT) polymerization in the presence of a chain transfer agent (CTA) and initiator. Carboxyl-terminated trithiocarbonate as a CTA was used to produce poly(n-BA) macro-CTA. The composition of the block copolymers was controlled by the ratio of the concentration of DPAA against the macro-CTA, its molecular weight, and polymerization time. The block copolymerization proceeded with controlled/living characteristics. Thermal and physical properties of the block copolymers were investigated by DSC, TGA and GPC. The morphologies of thin films of the block copolymers cast from solvent were examined by atomic force microscopy. |
