摘要： In one or more embodiments, the present invention provides a novel approach to the addition of plasticizers for softening TPUs, i.e., lowering the durometer and the melt viscosity. This approach involves incorporating bonded sulfonate groups with quaternary ammonium counterions into the TPU. In one or more embodiments of the present invention, the softening of TPU is achieved by incorporating an ionic diol, such as N,N-bis (2-hydoxyethyl)-2-aminoethane-sulfonic acid (BES), coupled with various bulky alkyl ammonium cations, during the chain extension step of the TPU synthesis. It is believed that that steric hindrance of the bulky quaternary ammonium groups weakens the dipole-dipole interactions of the sulfonate groups and/or lowers the crystallinity of the hard block, thereby creating additional free volume that softens the polymer and lowers the melt viscosity.

摘要： The present invention is directed to a covalently crosslinked hydrogel comprising the strain-promoted reaction product of an 8-member cycloalkyne functionalized polyalkylene glycol and a multi-arm glycerol exytholate triazide and methods for making them. Because the precursor materials can be manipulated without causing crosslinking, provided the strain threshold is not reached, these hydrogels permit mechanical control over when (and where) cross linking occurs and are easier to use than prior strain-activated or temperature-activated systems. These novel hydrogels do not require a catalyst to cross link, thus avoiding the biocompatibility problems common to many catalysts. Nor is the crosslinking process affected by the presence of catalysts or other substances, which have interfered with crosslinking in known strain induced hydrogels. Because of their crosslinking reaction kinetics, these novel hydrogels can encapsulate and transport highly sensitive cells and other biological additives and have no known toxic byproducts.
摘要翻译：本发明涉及一种共价交联的水凝胶，其包含8-元环炔官能化聚亚烷基二醇和多臂甘油异戊酸三叠氮化物的应变促进反应产物及其制备方法。因为前体材料可以在不引起交联的情况下被操纵，只要未达到应变阈值，这些水凝胶允许机械控制何时发生交联（并且在何处发生），并且比以前的应变活化或温度激活的系统更容易使用。这些新颖的水凝胶不需要催化剂交联，从而避免许多催化剂常见的生物相容性问题。交联过程也不受催化剂或其他物质的存在的影响，这些物质干扰已知应变诱导的水凝胶中的交联。由于它们的交联反应动力学，这些新颖的水凝胶可以包封和输送高敏感性细胞和其他生物添加剂，并且没有已知的有毒副产物。

摘要： A conductive elastomeric foam composite is presented, comprising an elastomer foam and polypyrrole, thiophene, or aniline and derivatives thereof. The foam is manufactured by first diffusing an oxidant into the dense polymer phase of a solvent-swollen foam and then diffusing pyrrole or pyrrole derivative vapor or solution into the dried foam, resulting in an in situ chemical oxidative polymerization of pyrrole at the oxidant site. Only about 5 wt % of conductive polymer is required for observing an insulator to conductor transition. The conductivity of the composite foam can be effectively controlled between 10.sup.-7 and 10.sup.-1 S/cm by varying either the amount of oxidant used and/or the copolymer composition.
