Title:
POLYMER FILM, MULTILAYER BODY AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2022/163776
Kind Code:
A1
Abstract:
A polymer film which has a layer A and a layer B that is arranged on at least one surface of the layer A, wherein: the layer A contains a polymer having a dielectric loss tangent of 0.01 or less, or at least one polymer A that is selected from the group consisting of a liquid crystalline polymer, a fluorine polymer, a polymerization product of a compound that comprises a cycloaliphatic hydrocarbon group and a group having an ethylenically unsaturated bond, a polyphenylene ether and an aromatic polyether ketone; the layer B contains an additive; and the layer B has an inflection point in the elastic modulus change due to temperature change or deformation rate change, or alternatively, the layer B is decreased in the elastic modulus when a pressure is applied thereto. A multilayer body which uses this polymer film; and a method for producing this multilayer body.
