Control of position and numbers of reactive functional groups in a structurally well-defined polymer has been a significant challenge, because such polymers would be useful for the fabrication of functional polymer materials with enhanced or new properties. We report here a synthesis of mid-chain functionalized polymers with controlled number average molecular weight and low molecular weight distribution by the photo-induced radical coupling reaction of polymers prepared by organotellurium-mediated living radical polymerization (TERP) in the presence of dienes.1 Since the number of the diene unit inserted in between two polymer chains was controlled, the number of functional groups at the mid-chain was also controlled by using functional dienes.Reference. 1. a) Yamago, S.
