    • The present invention provides a modified polyolefin type polymer having one structural unit having a glycidyl group represented by the following general formula (I) per 2-1,000 repeating units of olefin: ##STR1## (In the formula, Ar represents an aromatic hydrocarbon group 6-23 in carbon number having at least one glycidyloxy group, and R represents hydrogen atom or methyl group.), its manufacturing method and a resin composition containing the aforementioned modified polyolefin polymer. The polyolefin type polymer of the present invention is excellent not only in mechanical properties, heat resistance and resistance to oil, but also in dyeability, adhesiveness, antistatic property. It enables blending and conversion into alloys for its outstanding affinity with other resins.

    • A method of preventing scale formation and adhesion onto the surfaces of a polymerization vessel and auxilliary equipment used in polymerization of vinyl chloride monomer, wherein the surfaces are coated prior to polymerization with a coating agent having the concurrent properties of (a) one or more functional groups having the ability to chelate, (b) one or more functional groups having the ability to inhibit action of free radicals, and (c) substantial insolubility to vinyl chloride monomer and insoluble to water. The concurrent presences of these functional characteristics syngergistically act to prevent scale adhesion onto the surfaces after substantial numbers of repeated polymerization charges.
    • 一种防止水垢形成和粘合到聚合容器表面上的方法和用于聚合氯乙烯单体的辅助设备,其中表面在聚合前用具有(a)一种或多种功能性 具有螯合能力的基团,(b)一个或多个具有抑制自由基作用的官能团,和(c)对氯乙烯单体的大量不溶性并且不溶于水。 这些功能特征的同时存在同步地起作用以在大量重复的聚合装料之后防止水垢附着在表面上。
