The functional acrylamide tert-butyl N-acryloyl-â-alaninate
(M2b) was successfully homo-and block copolymerized for the
first time by a RAFT process using benzyl dithiobenzoate (BDTB)
as a chain transfer agent and 2,2’-azobis(isobutyronitrile)
(AIBN) as an initiator. The resulting homo-and block
copolymers have low polydispersities. Kinetic studies
demonstrated that the RAFT process of functional acrylamide
M2b proceeded in a controlled way at conversions below 50%.
The further investigation showed that BDTB was an effective
CTA for the RAFT-polymerization of functional acrylamides,
acrylates; however, it was not a suitable CTA for the
polymerization of functional methacrylic monomers.
