Title:
METHOD FOR PRODUCING MULTILAYER BODY, AND MULTILAYER BODY
Document Type and Number:
WIPO Patent Application WO/2020/204079
Kind Code:
A1
Abstract:
The present invention provides: a multilayer body which has excellent alkali resistance and excellent interlayer adhesion at high temperatures; and a method for producing a multilayer body. A method for producing a multilayer body, wherein a multilayer material having a layer of a first composition that contains a copolymer having a fluorine atom and a layer of a second composition that contains a non-fluorine polymer is prepared, and the first composition and the second composition are subsequently reacted with each other, thereby producing a multilayer body that has a first crosslinked layer that is produced from the first composition and a second crosslinked layer that is composed of a crosslinked product of the second composition. With respect to this method for producing a multilayer body, the absolute value of the difference between the SP value of the first composition and the SP value of the second composition is 0-3.0 (J/cm3)1/2.
