Title:
LAMINATE AND PRECURSOR LAMINATE
Document Type and Number:
WIPO Patent Application WO/2023/149500
Kind Code:
A1
Abstract:
The present invention provides a laminate having excellent dimensional stability after having been used in a high-temperature environment, and a precursor laminate constituting an uncrosslinked product thererof. The laminate according to the present invention has a first crosslinking layer and a second crosslinking layer. The first crosslinking layer includes a crosslinked product of a fluorine-containing copolymer A1, and optionally includes a crosslinked product of a non-fluoropolymer A2. The second crosslinking layer includes a crosslinked product of a fluorine-containing copolymer B1, and optionally includes a crosslinked product of a non-fluoropolymer B2. The combination of units based on monomers constituting the fluorine-containing copolymer A1 and the combination of units based on monomers constituting the fluorine-containing copolymer B1 differ from each other. The content MCA of the crosslinked product of the fluorine-containing copolymer A1 is greater than or equal to 85 mass% with respect to the total of the crosslinked product of the fluorine-containing copolymer A1 and the crosslinked product of the non-fluoropolymer A2. The content MCB of the crosslinked product of the fluorine-containing copolymer B1 is greater than or equal to 85 mass% with respect to the total of the crosslinked product of the fluorine-containing copolymer B1 and the crosslinked product of the non-fluoropolymer B2.
