可通过与非氟化乳化剂聚合获得的过氧化物可固化的含氟聚合物
摘要：
本发明公开了一种可固化含氟聚合物，该可固化含氟聚合物包含来源于VDF和TFE以及至少一种其它氟化共聚单体的重复单元，并且还包含–CF2CH2I端基和来源于用作改性剂的一种或多种全氟化双烯烃醚的支化位点，其中用作改性剂的所述一种或多种全氟化双烯烃醚符合以下通式：CF2‑CF‑(CF2)n‑O‑(R1)‑O‑(CF2)mCF＝CF2其中n和m彼此独立地为1或0，并且其中R1表示全氟化的直链或支链的环状或无环的脂族或芳族的烃残基，该烃残基可被一个或多个氧原子间断并且包含至多30个碳原子。还提供了制备所述可固化含氟聚合物的方法以及用于制备包含所述可固化聚合物的制品的方法。
摘要（英）：

Curable fluoropolymer containing repeating units derived from VDF and TFE and at least one other fluorinated comonomer and further containing -CF 2 CH 2 I end groups and branching sites derived from one or more perfluorinated bisolefinic ether(s) used as modifier(s), wherein the one or more perfluorinated bisolefinic ether(s) used as modifier(s) correspond to the general formula: €ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ CF 2 =CF-(CF 2 ) n -O-(R f )-O-(CF 2 ) m -CF=CF 2 wherein n and m are independent from each other either 1 or 0 and wherein R f represents a perfluorinated linear or branched, cyclic or acyclic aliphatic or aromatic hydrocarbon residue that may be interrupted by one or more oxygen atoms and comprises up to 30 carbon atoms. Further provided are methods of making the curable fluoropolymers and for making an article containing the curable polymers.
