  • POLYMERS HAVING BOTH HARD AND SOFT SEGMENTS, AND PROCESS FOR MAKING SAME
    Publication number: 20130041108
    Abstract: The present invention generally relates to alcohol- and amine-terminated polyisobutylene (PIB) compounds, and to a process for making such compounds. In one embodiment, the present invention relates to primary alcohol- and amine-terminated polyisobutylene compounds, and to a process for making such compounds. In still another embodiment, the present invention relates to polyisobutylene compounds that can be used to synthesize polyurethanes and polyureas, to polyurethane and polyurea compounds made via the use of such polyisobutylene compounds, and to processes for making such compounds. In yet another embodiment, the present invention relates to polyisobutylene compounds containing urea or urethane segments therein, and to a method of producing such compounds. In still yet another embodiment, the present invention relates to a polymer having one or more different soft segments and one or more different hard segments.
