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.

摘要： A PIB-based polymer network includes at least one sulfur containing segment and at least two PIB polymer segments. The at least two PIB polymer segments each include a core and at least two polyisobutylene polymer chains extending therefrom. The at least one sulfur containing segment includes at least one sulfur atom that is located between any two polyisobutylene polymer chains from two different PIB polymer segments, so that the sulfur containing segment connects those two different PIB polymer segments together. The PIB-based polymer network is produced by the thiol-ene reaction in the presence of light or heat. The reaction products include at least two polyisobutylene polymer precursor moieties, each polyisobutylene polymer precursor moiety having at least two end group selected from the end groups —CH2—CH(CH3)═CH2, —CH2═C(CH3)2, and —CH2—CH═CH2; and at least one multi-functional thiol.

摘要： In various embodiments, the present invention is directed to new low cost initiator compositions for use with the production of well-defined telechelic PIBs (by LC+P of isobutylene). In various other embodiments, the present invention is directed to methods for using these novel compositions as initiators for isobutylene (IB) and other cationically polymerizable monomers, such as styrene and its derivatives. In still other embodiments, the present invention is directed to structurally new, allyl (and chlorine) telechelic PIBs formed from these new initiator compositions and their derivatives (in particular, hydroxyl telechelic PIB and amine telechelic PIB). In yet other embodiments, the present invention is directed to structurally new polyurethanes, polyureas, and polyurethane ureas made using telechelic PIBs formed from these new initiator compositions.

摘要： A polyurea or polyurea-urethane elastomer comprises a soft polymer segment and a hard polymer segment, wherein the hard polymer segment includes polyurea groups in combination with H-bond accepting chain extenders (HACEs) to reduce the flow temperature (Tflow) while maintaining the excellent mechanical properties such that the resulting polyurea elatomer is rendered melt-processable.
