Document Type and Number:
WIPO Patent Application WO/2022/044592
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a resin composition that exhibits both excellent dry adhesiveness and wet adhesiveness, and that can be used for wet adhesion in a relatively wide range of temperatures. This resin composition which solves the above problem contains a plurality of types of vinylidene fluoride polymers. Of the plurality of types of vinylidene fluoride polymers, at least one type includes a structural unit including a carboxy group, and every one of the plurality of vinylidene fluoride polymers includes 95 mol% or more of a structural unit derived from vinylidene fluoride with respect to the total amount of structural units of the vinylidene fluoride polymer. The resin composition has the total melting calories of 20-50 J/g in a second round of heating in differential scanning calorimetry, and has an intrinsic viscosity of 2.5 dL/g or less.
