    • A polymeric material from the styrene family, consisting of macromolecular chains grafted by nitrogen-containing heterocyclic groups; wherein the macromolecular chains consist of a polymeric backbone to which a grafted agent is attached by at least one covalent bond, the grafting agent comprises, in a single molecule, one or more associative groups capable of being bound by hydrogen bonds, and one or more reactive groups capable of forming covalent bonds with the polymeric backbone, at least one of the associative groups of the modifier is an imidazolidone heterocyclic ring. The mean number of imidazolidone groups to be inserted into the macromolecular chains is dependent both on the mean mass of said chains and on the final properties to be imparted to the material. The polymeric material of the invention can be extruded, coextruded, injected, blow-moulded, moulded, overmoulded, calendered or thermoformed. Objects such as tubes, films, plates, stiffenerss, bottles and containers can be made. The polymeric material of the invention can also be blended with other materials such as other polymers, and can thus be modified by elastomeric phases that enhance the impact strength thereof. The polymeric material of the invention can be a component of masterbatches of additives such as pigments and fillers. The present invention further relates to the use of said polymeric material as a compatibilization agent in a composition including, inter alia, at least two polymers belonging to different polymeric classes.”
    • 来自苯乙烯家族的聚合物材料,由含氮杂环基团接枝的大分子链组成; 其中所述大分子链由接枝剂通过至少一个共价键连接的聚合物主链组成,所述接枝剂在单个分子中包含一个或多个能够被氢键结合的缔合基团,以及一个或多个 能够与聚合物主链形成共价键的反应性基团,改性剂的至少一个缔合基团是咪唑烷酮杂环。 插入大分子链中的咪唑烷酮基团的平均数目取决于所述链的平均质量和赋予材料的最终性能。 本发明的聚合物材料可以挤出,共挤出,注塑,吹塑,模制,包覆成型,压延或热成型。 可以制造诸如管,膜,板,扶强材,瓶和容器的物体。 本发明的聚合物材料还可以与其它材料如其它聚合物共混,并且因此可以通过增强其冲击强度的弹性体相改性。 本发明的聚合物材料可以是颜料和填料等添加剂母料的成分。 本发明还涉及所述聚合物材料在组合物中的相容剂的用途,所述组合物尤其包括属于不同聚合物类别的至少两种聚合物。

    • The invention concerns a polymer material consisting of macromolecular chains bound by hydrogen bonds wherein: the macromolecular chains consist of a polymer skeleton whereon is fixed by at least one covalent bond a modifying agent, the modifying agent comprising, assembled in a common molecule, one or more associative groups capable of being bound by hydrogen bonds and one or more reactive groups capable of forming covalent bonds with the polymer skeleton, at least one of the associative groups of the modifying agent is an imidazolidone heterocycle, the macromolecular chains bear on average 1 to 10 imidazolidone groups per chain. The average number of imidazolidone groups to be introduced into the macromolecular chains depends both on the average mass of said chains and the final properties desired for the material. The inventive polymer material can be extruded, co-extruded, injected, blown, moulded, overmoulded, calandered, thermoformed. It can be used to produce articles such as tubes, films, plates, extruded strings, bottles, containers. The inventive polymer material can also be mixed with other materials such as other polymers, thus it is used for example as impact modifier or rheology regulator. The invention further concerns the use of said polymer material as compatibility agent in a composition comprising among others at least two polymers belonging to different classes of polymers.
