摘要： The invention relates to a polymer composition as well as to a process for the preparation of such a composition wherein two or more essentially incompatible polymers, each containing functional hydroxy groups and/or functional amino groups, are in contact with each other in the presence of at least one compatibilizer, the compatibilizer being a carbonyl bislactam (CBL) having the structure according to formula (I), where n is an integer from 3 to 15 and preferably 5. Preferably, the compatibilizer is carbonyl biscaprolactam. Depending on the ratio of the number of functional —OH or —NH2 groups to the CBL, the composition can be used as a polymer dispersion, for instance for improvement of the impact resistance or of the VICAT, or as a copolymer. The invention also relates to shaped parts containing at least two parts that are in contact with each other via a boundary face, each of these parts comprising a different polymer, which polymers are essentially incompatible polymers and contain functional hydroxy groups and/or functional amino groups and with at least one of said polymers having reacted with carbonyl bislactam or containing carbonyl bislactam. The invention also relates to a process for the preparation of said shaped part. The shaped part can be prepared by means of coextrusion, insert moulding or overmoulding.
摘要翻译：本发明涉及一种聚合物组合物以及制备这种组合物的方法，其中两种或多种基本上不相容的聚合物（各自含有官能羟基和/或官能氨基）在存在下彼此接触至少一种增容剂，相容剂是具有式（I）结构的羰基双内酰胺（CBL），其中n为3至15的整数，优选为5。优选地，增容剂为羰基双己内酰胺。根据功能性-OH或-NH2基团与CBL的数量的比例，该组合物可用作聚合物分散体，例如用于改善耐冲击性或VICAT，或作为共聚物。本发明还涉及通过边界面彼此接触的至少两个部分的成形部件，这些部件中的每一个都包含不同的聚合物，该聚合物基本上是不相容的聚合物并且含有官能羟基和/或官能氨基并且所述聚合物中的至少一种与羰基双内酰胺或含有羰基双内酰胺反应。本发明还涉及一种用于制备所述成形部件的方法。成形部件可以通过共挤出，嵌入成型或包覆成型制备。
