摘要： The present invention is directed to a new class of thermoplastic elastomers (TPEs) and processes for making them. In some embodiments of the present invention, the end groups of the multi-arm PIB copolymer is a conjugated diene, whereas the other component is a multi-functional dienophile. The components of the TPE of the present invention are chemically connected via the well-known Diels-Alder reaction which is thermally reversible (by the retro-Diels-Alder reaction) at moderately elevated temperatures. The reversibility of the Diels-Alder retro-Diels-Alder reactions allows the recovery of the original components of the TPE and thus its recyclability and also gives the TPE the ability to be reshaped or reformed.

摘要： The present invention relates to novel hydroxyl-terminated polyisobutylenes and methods of making and using them. The hydroxyl-terminated polyisobutylenes contain a sulfur unit, —S—, within each terminal end group. The well-defined, sulfur containing, primary hydroxyl-terminated polyisobutylenes of the present invention can be simply, rapidly, and essentially quantitatively obtained by subjecting the unsaturated telechelic PIBs and mercapto alcohols to UV light-activated thiol-ene reactions. The resultant sulfur containing, primary hydroxyl-terminated polyisobutylenes can then be used in the production of polyurethanes and like materials.

摘要： Sulfur containing, hydroxyl-telechelic PIBs, hydrolytically and oxidatively resistant, biocompatible and biostable polyurethanes (PUs) made therefrom, and methods for making both are disclosed. Well-defined hydroxyl telechelic PIBs are synthesized by a thiol-ene click photochemical reaction between PIBs carrying unsaturated end groups and 2-mercaptoethanol (HS—CH2CH2—OH). This regioselective process affords HO—CH2CH2—S-PIB-S—CH2CH2—OH (abbreviated herein as HO—S-PIB-S—OH) in high yield. In some embodiments, these HO—S-PIB-S—OH polymers may be reacted with diisocyanates and a chain extender to form sulfur containing PIB-based PUs. These sulfur containing PIB-based PUs have been found to have properties and chemical stability that are very similar to that of PUs made from di-hydroxyl terminated PIBs (OH-PIB-OHs) without sulfur, but have surprisingly increased creep resistance and are easier and less expensive to make.

摘要： A polyisobutylene-based polymer network comprising the thiol-ene reaction product of at least two thiol-terminated polyisobutylene precursor polymers and at least one multi-functional allyl-containing precursor moiety or polymer in the presence of light or heat. The at least two thiol-terminated polyisobutylene precursor polymers have at least two thiol end groups. When each polyisobutylene precursor polymer has only two thiol end groups then the allyl-containing precursor moiety or polymer has at least three functional groups, and wherein when the allyl-containing precursor moiety or polymer has two functional groups then each polyisobutylene precursor polymer has at least three thiol end groups.

摘要： The present invention generally relates to polyurethanes and polyurethane nanocomposites having improved mechanical, rheological, and thermal properties over ordinarily produced polyurethanes and polyurethane nanocomposites. Such polyurethanes and polyurethane nanocomposites include very small amounts of a small chain diol, such as glycerol, and more specifically, between 0.01 and 4 weight percent of the small chain diol, based on the total polymer composition.
