    • The present invention relates to a process for preparing, by condensation, copolymers having polyamide blocks and polyether blocks in which polyamide blocks having dicarboxylic chain ends are mixed with: a polyether having two OH chain ends (a polyetherdiol), and a polyol having at least 3 OH functions. The copolymers have a higher molecular weight, higher mechanical properties (impact, processing, filmification etc), remain linear or only weakly branched. The multifunctionality of the polyol is only used for kinetic aspects. As regards the process, there is a reduction of cycle time, reduced technical requirements on the catalyst and vacuum system and a reduction of degradation which means a better colour stability. The invention also relates to these copolymers having polyamide blocks and polyether blocks and comprising in its chain the residues of a polyol having at least 3 OH functions.
    • 本发明涉及通过缩合制备具有聚酰胺嵌段和聚醚嵌段的共聚物的方法,其中将具有二羧酸链末端的聚酰胺嵌段与具有两个OH链末端的聚醚(聚醚二醇)和至少具有至少 3 OH功能。 共聚物具有较高的分子量,更高的机械性能(冲击,加工,成膜等),保持线性或仅有弱分支。 多元醇的多功能性仅用于动力学方面。 关于该方法,循环时间减少,催化剂和真空系统的技术要求降低,降解降低,这意味着更好的颜色稳定性。 本发明还涉及具有聚酰胺嵌段和聚醚嵌段的这些共聚物,并且在其链中包含具有至少3个OH官能团的多元醇的残基。

    • 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.
