    摘要： Shape memory polymers prepared by copolymerizing two monomers, which each separately produce polymers characterized by different glass transition temperatures in the presence of a difunctional monomer whereby the copolymer formed is cross-linked during the polymerization to form a theremoset network. The transition temperature of the final polymers is adjusted by the ratio of the monomers selected, to from about 20 to about 110° C., while the degree of cross-linking controls the rubbery modulus plateau. The shape memory polymers can be processed as castable formulations in the form of coatings and films. The copolymers are optically transparent and are useful as medical plastics. The invention also relates to the articles of manufacture thereof and methods of the preparation and use thereof.

    摘要翻译： 通过共聚两种单体制备的形状记忆聚合物，它们分别在双官能单体的存在下产生以不同玻璃化转变温度为特征的聚合物，由此形成的共聚物在聚合反应过程中交联以形成聚集体网络。 最终聚合物的转变温度通过所选单体的比例调节至约20至约110℃，而交联度控制橡胶模量平台。 形状记忆聚合物可以以涂料和薄膜的形式加工成可浇铸的制剂。 共聚物是光学透明的并且可用作医用塑料。 本发明还涉及其制造方法及其制备和使用方法。

    摘要： Chemically crosslinked polycyclooctene having excellent shape recovery properties and a method for its synthesis via ring-opening metathesis polymerization of cyclooctene using the dihydroimidazolylidene-modified Grubbs catalyst are disclosed. The polycyclooctene products, following curing with dicumyl peroxide can be shaped, the shape memorized, a new shape imparted with the original shape being recoverable by suitable temperature adjustment. The dependence of shape memory characteristics on degree of crosslinking was established. In addition to polycyclooctene, blends thereof with other materials such as SBR, EVA, polyurethane rubbers, and inorganic fillers can be utilized to provide chemically crosslinked products having excellent and tailored shape memory properties.
