Star-shaped macromolecules have been obtained by anionic block copolymerization of a monofunctional monomer and a divinyl compound with cumylpotassium or butyllithium as initiator. The polymer molecule is a crosslinked nodulus, to which n linear, sol

In a binary solvent mixture, the χ1 2 interaction parameter has a marked influence upon the intrinsic viscosity of a polymer. If χ 1 2 is positive, the [χ] value is higher than the weighted average of the viscosities measured in the pure constitue

Star polymer formation by sequential anionic copolymerization of styrene and divinylbenzene in a non-polar solvent (benzene) was re-examined. Kinetic investigations established that the core formation is rather slow. Moreover, once the star molecules

Ionic living polymerization methods are well suited for the synthesis of macromolecules of known structure, molecular weight and composition, and exhibiting low fluctuations in composition and in molecular weight. They were the first to allow the syn

The development of “macromolecular engineering” owes much to living anionic polymerizations. When carried out under conditions preventing spontaneous transfer and termination reactions, and with efficient initiators, these processes are well suit
