    • An electrostrictive graft elastomer (11) has a backbone molecule (12) which is a non-crystallizable, flexible macromolecular chain and a grafted polymer (13) forming polar graft moieties with backbone molecules. The polar graft moieties have been rotated by an applied electric field, e.g., into substantial polar alignment. The rotation is sustained until the electric field is removed. A process for producing strain in an elastomer includes: (a) providing a graft elastomer having a backbone molecule which is a non-crystallizable, flexible macromolecular chain and a grafted polymer forming polar graft moieties with backbone molecules; and (b) applying an electric field to the graft elastomer to rotate the polar graft moieties, e.g., into substantial polar alignment. The backbone molecule is preferably chlorotrifluoroethylene-rinylidene fluoride copolymer, and the grafted polymer is poly vinylidene fluoride or a copolymer thereof.
    • 电致伸缩接枝弹性体(11)具有骨架分子(12),其是不可结晶的柔性高分子链,和接枝聚合物(13)形成具有骨架分子的极性接枝部分。 极性接枝部分已经通过施加的电场旋转,例如进入基本极性对准。 旋转持续直到电场被去除。 用于生产弹性体中的应变的方法包括:(a)提供具有不可结晶的柔性大分子链的主链分子和形成具有主链分子的极性接枝部分的接枝聚合物的接枝弹性体; 和(b)向接枝弹性体施加电场以旋转极性接枝部分,例如进入基本的极性取向。 骨架分子优选为三氟氯乙烯 - 一偏二氟乙烯共聚物,接枝聚合物为聚偏二氟乙烯或其共聚物。

    • The preparation of allylated poly(vinyl chloride) by utilizing an allyltrialkylsilane in the presence of Friedel-Crafts acids is disclosed. The pendant allyl groups can be further reacted through various functionalization reactions to contain end groups such as epoxy and hydroxyl. Alternatively, an unsaturated group can be added to poly(vinyl chloride) utilizing a diene also in the presence of a Friedel-Crafts acid. These pendant groups can also be reacted to contain functional end groups such as hydroxyl and epoxy. In yet a further embodiment, the functionalized end groups such as pendant -OH groups of both the allylated and diene grafted poly(vinyl chloride) are further reacted with other monomers or polymer chains which thus results in a poly(vinyl chloride) chain having pendant monomers or polymers. These compositions are useful as compatibilizers for poly(vinyl chloride) and various other resins.
    • 公开了在Friedel-Crafts酸存在下利用烯丙基三烷基硅烷制备烯丙基化聚(氯乙烯)。 侧链烯基可以通过各种官能化反应进一步反应以包含端基如环氧基和羟基。 或者,在Friedel-Crafts酸的存在下,也可以使用二烯也可以将不饱和基团加入到聚(氯乙烯)中。 这些侧基也可以反应以含有官能端基,例如羟基和环氧基。 在又一个实施方案中,官能化的端基如烯丙基化和二烯接枝的聚(氯乙烯)的侧基-OH基团进一步与其它单体或聚合物链反应,从而导致具有侧基的聚(氯乙烯)链 单体或聚合物。 这些组合物可用作聚(氯乙烯)和各种其它树脂的增容剂。
