    摘要: The present invention generally relates to alcohol-terminated polyisobutylene (PIB) compounds, and to a process for making such compounds. In one embodiment, the present invention relates to primary alcohol-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, to polyurethane 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 primary alcohol-terminated polyisobutylene compounds having two or more primary alcohol termini and to a process for making such compounds. In yet another embodiment, the present invention relates to primary terminated polyisobutylene compounds having two or more primary termini selected from amine groups or methacrylate groups.

    摘要: The present invention generally relates to singly-terminated polyisobutylene (PIB) compounds, and to a process for making such compounds. In one embodiment, the present invention relates to singly-terminated polyisobutylene compounds that contain only one primary alcohol, amine, or methacrylate group as the single-terminating group. In another embodiment, the present invention relates to singly-terminated polyisobutylenes carrying exactly one terminal alcohol, amine, or methacrylate group, where such singly-terminated polyisobutylenes have a number average molecular weight of about 500 to about 5000 grams per mole. In still another embodiment, the present invention relates to singly-terminated polyisobutylene compounds that can be used to synthesize polyurethanes, to polyurethane compounds made via the use of such polyisobutylene compounds, and to processes for making such compounds.

    摘要: In one or more embodiments, the present invention provides a method for forming allyl telechelic polyisobutylene polymers having well defined molecular weights and molecular weight distributions using living cationic polymerization under ideal temperature control using a mixture of polar and nonpolar refluxing solvents. The methods according to various embodiments of the present invention provide temperature control that approaches the ideal, i.e., the heat of polymerization is instantaneously absorbed by the medium and the temperature of the system remains unchanged. The heat generated during the exothermic polymerization of isobutylene is released as an increase in the rate of reflux, rather than the temperature, since the temperature is set by the boiling point of the system and does not change.
