Polycondensation of 4,4'-azobis-4-cyanovaleryl chloride and :t,co-bis(3-hydroxypropyl)polydimethylsiloxane was carried out to yield poly(azo-containing siloxane ester)s. These were used to induce the radical polymerization of various vinyl monomers through the thermal decomposition of the azo groups
## Abstract **Summary:** The free‐radical addition of __ω__‐functional mercaptans to the vinyl double bonds of 1,2‐polybutadiene‐__block__‐poly(ethylene oxide) copolymers was used for modular synthesis of well‐defined functional block copolymers. The modification reaction proceeds smoothly and yiel
