    摘要： Polymers containing ketone groups such as hydroesterified 1,3-butadiene polymers, including styrenic block copolymers, are hydrogenated with a cobalt/aluminum catalyst which substantially converts ketone groups to alcohol groups and improves polymer stability.

    摘要： Polymerized 1,3-butadiene, including styrenic block copolymers, are functionalized with both carboxylic ester groups and ketone linking groups by reaction with carbon monoxide and an alcohol. Such conjugated diene polymers can be reacted in the presence of a catalyst composition that includes a cobalt compound and an amine ligand. The functionalized 1,3-butadiene polymers may be hydrogenated with a nickel/aluminum catalyst which removes olefinically unsaturated carbon-carbon bonds without substantially hydrogenating the ketone linking groups and carboxylic ester groups.

    摘要： A method for preparing hydrogenated polymers containing acidic functionality in a portion thereof initially containing ethylenic unsaturation from a polymer containing ethylenic unsaturation or both aromatic and ethylenic unsaturation comprising the steps of first incorporating an acidic functional group precursor radical into the polymer, hydrogenating at least a portion of the ethylenic unsaturation contained in the polymer containing the acidic functional group precursor radicals and then converting at least a portion of the acidic functional group precursor radicals to the corresponding acidic functional group. In general, any acidic functional group precursor radical which will have less of an impact upon the hydrogenation reaction than the corresponding acidic functional group may be used. Best results are, however, achieved when acidic functional group precursors are used which are relatively neutral and which do not react or complex with the metal compounds used to prepare the catalyst or resulting from the combination of such metal compounds. The catalyst used to effect the hydrogenation will be prepared by combining a compound, preferably an alkoxide or carboxylate, of an iron group metal with an alkyl or a hydride containing a Group I-A, II-A or III-B metal. Preparation of the catalyst is preferably accomplished in the presence of water. Best results are achieved when the acidic functional group precursor is a metal salt and the metal salt and the reducing component used to prepare the catalyst contain the same metal. Depending upon the particular catalyst employed and the acidic functional group precursor radical used, up to about 90-95% of the ethylenic unsaturation initially contained in the polymer can be converted or hydrogenated.

    摘要： A thermoplastic polymer having good tensile strength at elevated temperatures is obtained by modifying a block copolymer composed of a conjugated diene compound and an alkenyl arene compound. The block copolymer is first selectively hydrogenated and thereafter modified by grafting silicon or boron containing functional groups primarily in the alkenyl arene block via metalation. Each silicon containing functional group preferably contains at least two functional groups which allow crosslinking by condensation reactions.
