    • A process is provided for metallating crystalline ethylene polymers which have polymerized therein a minor amount of at least one nonconjugated diene and, optionally, a minor amount of at least one 1-olefin. Metallation is accomplished with an alkyllithium compound and at least one activating reagent after a slurry of the copolymer in a nonreactive, saturated, nonpolar hydrocarbon solvent is first heated to a temperature greater than 80.degree. Centigrade to provide the polymer with an expanded settling volume greater than its original settling volume. Metallation may be accomplished either at that temperature or at a lower temperature following cooling of the slurry. The activating reagents include potassium alkoxides, and chelating tertiary diamines. The metallated polymers so prepared may be reacted with (a) one or more anionically polymerizable monomers to form graft polymers or (b) a reagent such as carbon dioxide to form a functionalized polymer.
    • 提供了一种金属化结晶乙烯聚合物的方法,其中聚合有少量至少一种非共轭二烯和任选的少量至少一种1-烯烃。 在非反应性饱和非极性烃溶剂中的共聚物浆液首先被加热至高于80℃的温度之后,用烷基锂化合物和至少一种活化剂进行金属化,以使聚合物的膨胀沉降体积大于 其原始定居量。 金属化可以在该温度下或在冷却浆料后的较低温度下完成。 活化试剂包括烷醇钾和螯合叔二胺。 如此制备的金属化聚合物可以与(a)一种或多种阴离子可聚合单体反应形成接枝聚合物或(b)诸如二氧化碳的试剂以形成官能化聚合物。

    • A process is provided for metallating ethylene polymers which have polymerized therein a minor amount of nonconjugated diene. Metallation is accomplished with a blend of three metallating reagents: (a) an alkyllithium compound; (b) a potassium alkoxide; and (c) a chelating tertiary diamine. The metallated polymers so prepared may be reacted with one or more anionically polymerizable monomers to form graft polymers or with a reagent such as carbon dioxide to form a functionalized polymer. When the anionically polymerizable monomer has two or more polymerizable sites, the metallated polymer is reacted with a modifying compound such as alpha-methylstyrene before it is reacted with the monomer(s). Certain of the graft polymers behave as thermoplastic elastomers whereas others are thermoplastic. The blend of metallating reagents may be used with any polymer having partial or complete unsaturation.
    • 提供了一种金属化乙烯聚合物的方法,其中聚合有少量非共轭二烯。 金属化是用三种金属化试剂的混合物完成的:(a)烷基锂化合物; (b)醇钾; 和(c)螯合叔胺。 如此制备的金属化聚合物可以与一种或多种阴离子可聚合单体反应以形成接枝聚合物或与诸如二氧化碳的试剂形成官能化聚合物。 当阴离子聚合单体具有两个或更多个可聚合位点时,金属化聚合物在与单体反应之前与诸如α-甲基苯乙烯的改性化合物反应。 某些接枝聚合物表现为热塑性弹性体,而另一些则是热塑性弹性体。 金属化试剂的混合物可以与具有部分或完全不饱和度的任何聚合物一起使用。
