    摘要： Block copolymers useful in formulations of adhesives, coatings, and lubricating oils have a particular structure comprising blocks of a polymerized alkenyl aromatic compound such as styrene, an internal block of a polymerized conjugated alkadiene such as butadiene, as well as selectively hydrogenated derivatives thereof, and a polar block of a polymerized alkyl methacrylate such as t-butyl methacrylate.

    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： Elastomeric polymers comprising at least one alkali metal atom are modified by incorporating at least one group capable of sterically hindering coupling reactions which frequently occur when functional groups are subsequently incorporated into such polymers. In general, the group capable of sterically hindering coupling reactions may be incorporated by reacting the elastomeric polymer comprising at least one alkali metal atom with a compound containing a group capable of reacting with the elastomeric polymer at one end and at least one pendant group larger than hydrogen at the other. Groups that will react with elastomeric polymers comprising at least one alkali-metal atom are of course, well known, in the art, and include groups containing sulfur, oxygen, nitrogen and the like and ethylenically and acetylenically unsaturated groups. Compounds containing terminal ethylenically unsaturated groups are particularly useful in preparing the modified elastomeric polymers of this invention. Terminal groups capable of sterically hindering coupling reactions, generally, include all groups larger than hydrogen. Hydrocarbon groups are, however, particularly useful since these generally do not alter the properties which are characteristic of the elastomeric polymers. Aromatic groups containing at least 6 carbon atoms or cyclic hydrocarbon groups containing at least 5 carbon atoms are particularly effective. 1,1-diphenyl ethylene is particularly preferred in the present invention. Elastomeric polymers which have been modified in accordance with this invention may then be functionalized with less risk of undesirable coupling.
