A process has now been discovered that permits the simultaneous crosslinking and derivation of an, optionally hydrogenated, polymer whose backbone is composed of a conjugated diene, an unsaturated nitrile and an unsaturated carboxylic acid in the presence of a coupling/condensing agent. This permits the preparation of a novel polymeric material that is an optionally hydrogenated polymer of a conjugated diene, an unsaturated nitrile and a derived unsaturated acid. It has also been found that this novel polymeric material has unexpected and valuable properties. |

Improved amine-terminated polybutadienes (ATPBs) having one or two terminal groups of the formula nullCHRNH2 wherein R is C1-C20 alkyl, are prepared by aminating a secondary hydroxyl-terminated polybutadiene having no ether groups. The ATPBs may be hydrogenated or partially hydrogenated, either prior to or after the amination, to saturate or partially saturate the polymers. Preferred ATPBs are of the formula H2NCHR-(polybutadiene)-CHRNH2 wherein R is C1-C20 alkyl. Polyureas, polyurethanes, crosslinked epoxies, polyamides, and other derivatives with improved properties can be prepared from the ATPBs. The resultant derivatives are useful in liquid binders for braking systems, electric potting compositions, coatings, adhesives, sealants, and water proofing membranes, for example. |

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. |
