Otsu, Takayuki published the artcilePolymer design by iniferter technique in radical polymerization: synthesis of AB and ABA block copolymers containing random and alternating copolymer sequences, Synthetic Route of 3052-61-7, the publication is Polymer Journal (Tokyo, Japan) (1985), 17(1), 97-104, database is CAplus.
The iniferter (initiator-transfer agent-terminator) technique was applied to the synthesis of the AB and ABA block copolymers containing various random and alternating copolymer sequences. Monomeric photoiniferters used were of general formula Ar[CH2SC(:S)NEt2]x [Ar = Ph, x = 1, (I) [3052-61-7]; Ar = 1,4-C6H4, x = 2, (II) [89964-93-2]; and Ar = 1,2,4,5-C6H2, x = 4, (III) [92687-20-2]]. Polymeric photoiniferters were prepared by photolysis of I, II, and III. The photopolymerizations with I and II proceeded via a living radical mechanism III and gave soluble mono- and bifunctional polymers, resp. However, III induced living radical polymerization of styrene with gelation. When various polymers and copolymers obtained by I and II were used as polymeric photoiniferters, the AB and ABA block copolymers containing random copolymer sequences were obtained in high yields. Similarly, the alternating copolymerization of iso-Bu vinyl ether with maleic anhydride in the presence of alternating copolymers (e.g., styrene and di-iso-Pr fumarate), which were obtained with I and II, as polymeric photoiniferters gave the AB and ABA block copolymers consisting of alternating copolymer sequences. III and the polymers and copolymers obtained by III could also act as an excellent crosslinking agent.
