Abstract
Official abstract text for this publication.
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 group.
First claim
Opening claim text (preview).
What is claimed is: 1. A primary amine-terminated polyisobutylene compound according to the following formula: where n and m are each independently selected from an integer in the range of from 2 to about 5,000. 2. The primary amine-terminated polyisobutylene compound of claim 1 , wherein n is and m are each independently selected from an integer in the range of from about 7 to about 4,500. 3. The primary amine-terminated polyisobutylene compound of claim 1 , wherein n is and m are each independently selected from an integer in the range of from about 10 to about 4,000. 4. The primary amine-terminated polyisobutylene compound of claim 1 , wherein n is and m are each independently selected from an integer in the range of from about 15 to about 3,500. 5. The primary amine-terminated polyisobutylene compound of claim 1 , wherein n is and me are each independently selected from an integer in the range of from about 25 to about 3,000. 6. The primary amine-terminated polyisobutylene compound of claim 1 , wherein n is and m are each independently selected from an integer in the range of from about 75 to about 2,500. 7. The primary amine-terminated polyisobutylene compound of claim 1 , wherein n is and m are each independently selected from an integer in the range of from about 100 to about 2,000. 8. The primary amine-terminated polyisobutylene compound of claim 1 , wherein n is and m are each independently selected from an integer in the range of from about 250 to about 1,500. 9. The primary amine-terminated polyisobutylene compound of claim 1 , wherein n is and m are each independently selected from an integer in the range of from about 500 to about 1,000.
