The present invention relates primarily to polymers comprising at least one alkenyl aromatic monomer, at least one conjugated diene monomer, and at least one monomer containing silyl hydride moieties, characterized in that said polymers are hydrogenated and preferably functionalized by hydrosilylation reactions between the silyl hydride groups on the polymer chain and the multiple bonds of any alkene or alkyne compound. Besides the described products, this invention comprises their synthesis processes and their uses, especially as thermofusible adhesives, in plastics impact modification, and in chain-extension reactions to obtain new materials, among others.

Hydrogenated alkenyl aromatic-diene copolymers containing comonomers having silyl hydride units and their functionalized analogs

The preparation of novel fullerynes which are fullerenes (e.g. C, C, C, etc.) that contain one or more alkyne functionalities and may contain additional functional groups such as hydroxyls, halogens, esters, haloesters, phenyl, oligo(ethylene glycol)s, perfluorinated alkyl chains, and the like. Two desired preparation routes are disclosed. The first one is the Fischer esterification in desired solvents using a special designed reactor in contrast to the heretofore initial Steglich reaction that results in side reactions and low yields. The second one uses acetylide Grignard reagents that have reduced nucleophilicity and higher stability in contrast to the use of heretofore initial lithium organyls or other Grignard reagents that would add to Cwith possible multi-additions in an uncontrollable manner.

Process and method for the efficient preparation of fullerynes

A method is provided for synthesizing a polymer that has highly-functionalized chain-end moieties. The method functionalizes liquid rubber to terminate a metallic or organometallic initiated living polymer. After the living polymer has been terminated with the functionalized liquid rubber, the functionalities on the residue of the liquid rubber are preferably modified to yield more advantageous functionalities.

A method is provided for polymerizing oxiranes by employing a lithium-containing polymerization initiator in a liquid reaction medium devoid of polymerization additives. Linear and star polymers can be produced by practicing the subject method.
