• Nitroxide Compounds for Minimizing Scorch in Crosslinkable Compositions
  申请人：Esseghir Mohamed

  公开（公告）日：2008-04-10

  Scorch is inhibited during the free-radical crosslinking of a crosslinkable polymer, e.g., an EPDM, by incorporating into the polymer before melt processing and crosslinking a scorch inhibiting amount of a derivative, preferably an ether, ester or urethane derivative, of a TEMPO compound, e.g., 4-hydroxy-tetrahydrocarbylpiperidin-1-oxyl. The scorch inhibitors of this invention perform as well, if not better, than their 4-hydroxy-tetrahydrocarbylpiperidin-1-oxyl counterparts in similar polymer compositions and under similar conditions in terms of scorch inhibition and ultimate degree of crosslinking, but exhibit less volatility and less migration within the polymer composition.

  在可交联聚合物（例如EPDM）的自由基交联过程中，通过在熔融处理和交联之前将TEMPO化合物的衍生物（优选为醚、酯或脲衍生物）的防燃剂添加到聚合物中，可以抑制烧焦。本发明的防燃剂在类似的聚合物组合物和相似条件下，与其4-羟基四氢碳基哌啶-1-氧基衍生物相比，在防燃和最终交联程度方面表现得同样好，甚至更好，但在聚合物组合物中挥发性和迁移性都较小。

• Alkyl-substituted polymers having enhanced albumin affinity

  公开（公告）日：1982-09-29

  Methods and compositions are provided for selectively enhancing the affinity of albumin for the surface of polymeric materials. Reactive alkyl chains having C8-C30 residues are covalently attached directly to polymeric materials such as polyamides, polyesters, polyacrylamides, and polyurethanes. Reactive alkyl compounds include alkyl halides, alkyl sulfonates, alkyl isocyanates, and alkyl amines. Alternatively, intermediate bifunctional arms, e.g. toluene- diisocyanate, can be used to link the alkyl chains to the menc polymer precursors which, following polymerization, are available for albumin binding without postpolymenzation modification. The resulting compositions when im plemented in conjunction with blood products selectively enhance albumin surface affinity-binding to the exclusion of other blood components, and subsequent thrombus formation is prevented.

  本发明提供了选择性增强白蛋白对聚合物材料表面亲和力的方法和组合物。具有 C8-C30 残基的活性烷基链可直接共价连接到聚酰胺、聚酯、聚丙烯酰胺和聚氨酯等聚合物材料上。活性烷基化合物包括烷基卤化物、烷基磺酸盐、异氰酸烷基酯和烷基胺。另外，也可使用双官能团中间臂（如甲苯二异氰酸酯）将烷基链连接到孟克聚合物前体上，聚合后的孟克聚合物前体无需进行聚合后修饰即可与白蛋白结合。由此产生的组合物在与血液制品一起使用时，可选择性地增强白蛋白表面的亲和力，从而将其他血液成分排除在外，防止血栓的形成。
