H. Terada et al., SYNTHESES OF MACRO-AZO-INITIATORS COMPOSED OF POLYISOPRENE OR HYDROGENATED POLYISOPRENE, Pure and applied chemistry, A31, 1994, pp. 173-178
Prepolymers such as polyisoprene diol and hydrogenated polyisoprene di
ol were condensed with 4,4'-azobis(4-cyanopentanoyl chloride) to prepa
re macro-azo-initiators. Their thermal decomposition behavior, measure
d by differential scanning calorimeter, were similar to each other. Th
ese macro-azo-initiators were capable for block copolymerization of vi
nyl monomers such as styrene and methyl methacrylate.
