发明名称 Fluid transfer member
摘要 The present invention provides a fluid transfer member having thermal stability on the occasion of molding, stress cracking resistance and low liquid chemical permeability at the same time. The present invention is a fluid transfer member which is composed by a laminate containing a layer [P] comprising a fluoropolymer and/or a fluorine-free organic material and a layer [Q] comprising a chlorotrifluoroethylene copolymer.

主权项 1. A fluid transfer member which is composed by a laminate containing a layer [P] comprising a fluoropolymer and/or a fluorine-free organic material and a layer [Q] comprising a chlorotrifluoroethylene copolymer, wherein the chlorotrifluoroethylene copolymer is a chlorotrifluoroethylene copolymer consisting of chlorotrifluoroethylene unit, tetrafluoroethylene unit and a monomer [B] unit derived from a monomer [B] copolymerizable with chlorotrifluoroethylene and tetrafluoroethylene, wherein the sum of said chlorotrifluoroethylene unit and said tetrafluoroethylene unit amounts to 90 to 99.9 mole percent and said monomer [B] unit amounts to 10 to 0.1 mole percent, wherein said chlorotrifluoroethylene unit amounts to 12.4 to 61.6 mole percent of units constituting the chlorotrifluoroethylene copolymer, wherein said monomer [B] is at least one monomer selected from the group consisting of a perfluoro(alkyl vinyl ether) and a vinyl monomer represented by the general formula (I): CX3X4═CX1(CF2)n—X2  (I) wherein X1, X3 and X4 are the same or different and each represents hydrogen atom or fluorine atom, X2 represents hydrogen atom, fluorine atom or chlorine atom and n represents an integer of 1 to 10, the temperature required for 1% by mass of the chlorotrifluoroethylene copolymer to be decomposed is not lower than 380° C.
