Improved amine-terminated polybutadienes (ATPBs) having one or two terminal groups -CHRNH2, more particularly of the formula H2NHRC-(polybutadiene)-CHRNH2, 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. Polyureas, polyurethanes, crosslinked epoxies, polyamides, and other derivatives with improved properties are 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.
