摘要： This invention discloses a process for selectively hydrogenating double bonds in unsaturated polymers, such as polybutadiene. The utilization of the process of this invention results in a rate of vinyl hydrogenation which is slowed relative to the rate of backbone hydrogenation. By utilizing the process of this invention, the rate of hydrogenation of double bonds in the polymers is satisfactory. The process of the subject invention more specifically comprises contacting a polymer containing double bonds in its backbone and vinyl unsaturation with hydrogen in the presence of a polymer containing pendant groups having the structural formula --Rh(P.phi..sub.3).sub.2 X wherein .phi. represents a phenyl group and wherein X represents a halogen atom. Polymers having pendant --P.phi..sub.2 --Rh(P.phi..sub.3).sub.2 X groups are highly preferred catalysts for utilization in the selective hydrogenations of this invention.

摘要： Syndiotactic 1,2-polybutadiene can be blended with various rubbers in order to improve the properties thereof. For instance, syndiotactic 1,2-polybutadiene can be blended with rubbers utilized in making tire treads in order to improve the heat build-up and wear characteristics of tires. The interaction and adhesion between syndiotactic 1,2-polybutadiene and rubbers can be improved by carboxylating the syndiotactic 1,2-polybutadiene. The presence of carboxylic acid groups on the syndiotactic 1,2-polybutadiene also greatly improves interaction with fillers commonly utilized in rubber compounding, such as carbon black. This invention discloses a process whereby syndiotactic 1,2-polybutadiene can be easily and inexpensively carboxylated. This invention more specifically discloses a method for preparing carboxylated syndiotactic 1,2-polybutadiene which comprises: (1) reacting syndiotactic 1,2-polybutadiene with hydrogen and carbon monoxide in an organic medium to produce formyl syndiotactic 1,2-polybutadiene, wherein the syndiotactic 1,2-polybutadiene is in the form of small particles having a particle size of less than about 250 microns which are suspended in the organic medium; and (2) reacting the formyl syndiotactic 1,2-polybutadiene with oxygen to produce the carboxylated syndiotactic 1,2-polybutadiene.
