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

New results are given on the physical gelation of atactic polystyrene-CS 2 solutions in relation to the structure of the chains. We demonstrate here the starlike effect on the onset of gelation supported by well-improved techniques such as the ball-d

The reaction of sec-butyllithium with 1,1-bis(4-isopropenylphenyl)-1-phenyltridecane (3) yields carbanionic species which are soluble in a non-polar solvent. The long hydrocarbon “tail” of the molecule and the tendency of the organolithium compou

La chromatographie en phase liquide, par impregnation d’un gel reticule, est devenue en peu de temps une technique fort utilisee pour l’etude de la polydispersite de substances macromoleculaires. Toutefois l’etalonnage de l’appareil pose quel

Star-shaped polystyrene samples have been synthesized by anionic block-copolymerization of styrene and divinylbenzene (DVB), the proportion of the latter monomer being of the order of a few molecules per living end. Vacuum technique was used and benz
