    • Disclosed are processes for preparing an epoxidized and/or hydroxylated α- oléfine/diène copolymer materials such as ethylene/dicyclopentadiene. These processes comprise contacting in a reaction medium a) a copolymeric precursor component with b) a hydrogen peroxide oxidizing agent, in the presence of alkyl-trioxorhenium-based catalyst, under certain reaction conditions. The copolymeric precursor component comprises copolymers of α-olefins and dienes with these copolymers containing at least one double bond in each diene-derived comonomer. The reaction medium is maintained under reaction conditions which promote formation of oxirane rings at, and/or diol formation across, the sites of the diene-derived co-monomer double bonds in the copolymeric precursor material. Epoxidation and hydroxylation generally increases the glass transition temperature, T g , of these copolymers and imbues polarity which imparts oil resistance. Functionalization in this manner thus provides a different balance between properties, cost, and processing range, and can make the resulting functionalized polyolefin materials especially useful as oil resistant, thermally stable elastomers or as structural engineering thermoplastics or precursors thereof.
    • 公开了制备环氧化和/或羟基化的二醇/二烯共聚物材料如乙烯/二环戊二烯的方法。 这些方法包括在一定反应条件下,在烷基 - 三氧铼基催化剂存在下,使反应介质a)共聚物前体组分与b)过氧化氢氧化剂接触。 共聚前体组分包括α-烯烃和二烯与这些共聚物在每个二烯衍生的共聚单体中含有至少一个双键的共聚物。 反应介质保持在促进在共聚物前体材料中二烯衍生的共聚单体双键的位置和/或二醇形成环氧乙烷环的反应条件下。 环氧化和羟基化通常增加这些共聚物的玻璃化转变温度,并赋予赋予耐油性的极性。 因此,以这种方式的功能化在性能,成本和加工范围之间提供了不同的平衡,并且可以使得到的官能化聚烯烃材料特别用作耐油,热稳定的弹性体或作为结构工程热塑性塑料或其前体。

    • A process for producing an epoxidized diene polymer which comprises: dispersing or suspending a diene polymer (C) having a particle diameter in terms of sphere diameter of 0.05 to 20 mm either in a medium (A) in the presence of powder particles (B) insoluble therein or in a water medium in the presence of a phenolic stabilizer and/or phosphorus compound stabilizer; and epoxidizing the diene polymer (C) in the dispersed or suspended state with an epoxidizing agent. Thus, an epoxidized diene polymer having excellent thermal stability is obtained. By the process, the epoxidation of the diene polymer (C) in a solid state and the production and purification of the target polymer are economically conducted. The process is free from various problems associated with the epoxidation of a diene polymer dissolved in a solvent.
