ABSTRACT:
Selectively hydrogenated block polymers of an alkenyl aromatic compound and a conjugated alkadiene are functionalized by the presence of a plurality of carbamoyl substituents on aromatic rings in the aromatic portion of the polymer. Such carbamoyl-functionalized derivatives are produced by reaction of corresponding carboxylic acid-functionalized polymers by reaction with ammonia followed by application of heat. The carbamoyl-substituted polymers exhibit improved properties and form blends with engineering thermoplastics.
