Abstract:
Improved amine-terminated polybutadienes (ATPBs) having one or two terminal groups of the formula —CHRNHwherein R is C-Calkyl, 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 animation, to saturate or partially saturate the polymers. Preferred ATPBs are of the formula HNCHR-(polybutadiene)-CHRNHwherein R is C-Calkyl. 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.
