“…In particular, addition products of dialkylaluminium hydrides to random styrene (25%)/butadiene copolymers have been studied in detail. 51,52 Organoaluminium compounds can undergo insertion into the multiple bonds of functional groups of the polymeric constituents of PPC. 44 Most likely, immobilisation of alumoxanes proceeds by the same mechanism.…”

“…Though the hydrosilylation of olefins has been widely studied, [1][2][3][4][5][6] only a few studies of fatty acid esters have been reported. [7][8][9][10][11][12][13][14][15][16][17] These interesting studies did not include complete analytical details of the compounds synthesized, and did not examine the regioselectivity of the reactions. Therefore, we decided to complete and extend these studies to fatty acid methyl esters (FAMEs) and crude fish oil.…”

Hydrosilylation of fatty acid methyl esters (FAMEs) were efficiently catalyzed by Speier's and Wilkinson's catalysts in the case of vinylic acid esters, but less efficiently in the case of non-vinylic ones, which gave non-regiospecific additions. In the latter case, initiation by radicals led to regiospecific reactions for oleic esters (C10-silylation). This regiospecificity can be attributed to the higher stability of the C10-silylated adduct and of the corresponding radical intermediate. Only regioselective addition was observed for linoleic esters (C13-silylation % 70%, C10 % 20%, C9 % 10%). Molecular modeling was used to examine the stability of the isomeric products and radicals. The new concept of radical initiation sequence has been successfully applied to FAMEs and then was extended to crude fish oil.

The synthesis of graft copolymers by anionic polymerization techniques is reviewed. Two basic procedures are described. In one a polymer having a reactive end‐group is prepared and allowed to react with another polymer having suitable functional groups. In the second procedure, anions are generated on a preformed polymer backbone and used to initiate the polymerization of subsequently added monomers.
