Title:
LAMINATE AND COPOLYMER
Document Type and Number:
WIPO Patent Application WO/2018/047477
Kind Code:
A1
Abstract:
Provided is a laminate in which a fluororesin layer and a rubber layer are strongly bonded to each other, the fuel permeability of the fluororesin layer is low, and solvent cracking is unlikely to occur in the fluororesin layer. This laminate contains a rubber layer (A) and a fluororesin layer (B), and is characterized by the following: the fluororesin layer (B) containing a copolymer containing chlorotrifluoroethylene units, tetrafluoroethylene units and perfluoroalkyl vinyl ether units; the copolymer containing chlorotrifluoroethylene units and tetrafluoroethylene units at a quantity of 96.0-97.4 mol.% relative to all the monomer units that constitute the copolymer; and containing the perfluoroalkyl vinyl ether units at a quantity of 2.6-4.0 mol.% relative to all the monomer units that constitute the copolymer.
