摘要： The invention relates to core-shell particles, said particles comprising: a core consisting essentially of at least one tetrafluoroethylene (TFE) polymer [polymer (F)], said core having an average primary particle size of less than 100 nm a shell consisting essentially of at least one high performance polymer [polymer (HPP)], wherein the polymer (HPP) is chosen among polycondensation polymers that have a heat deflection temperature (HDT) of above 80° C. under a load of 1.82 MPa when measured according to ASTM D648. The core-shell particles of the invention advantageously allow obtaining molded articles with homogeneous properties, both when used alone and when used as additive, as they generally do not undergo segregation phenomena.Still objects of the inventions are the process for manufacturing said core-shell particles, the use of said particles as additives, the composition and the articles thereof.
摘要翻译：本发明涉及核 - 壳颗粒，所述颗粒包括：主要由至少一种四氟乙烯（TFE）聚合物[聚合物（F）]组成的芯，所述芯的平均初级粒径小于100nm，壳基本上的至少一种高性能聚合物[聚合物（HPP）]，其中聚合物（HPP）选自在1.82MPa的负载下具有高于80℃的热变形温度（HDT）的缩聚聚合物，当根据 ASTM D648。本发明的核 - 壳颗粒有利地获得具有均匀性质的成型制品，当它们单独使用和用作添加剂时，因为它们通常不会发生分离现象。本发明的另一个目的是制造所述核 - 壳颗粒的方法，所述颗粒作为添加剂的用途，组合物和制品。
