측쇄에 탄소수 3 내지 10의 알킬기를 갖는 올레핀 단위를 포함하는 환상 올레핀계 수지 (A)와 염소 함유 수지 (B)를 포함하는 수지 조성물로 수지 필름을 형성한다. 상기 염소 함유 수지 (B)는 염화비닐리덴계 중합체여도 된다. 상기 염소 함유 수지 (B)의 비율은, 환상 올레핀계 수지 (A) 100중량부에 대하여, 0.5 내지 60중량부여도 된다. 이 필름은, 고체 고분자형 연료 전지의 전해질막 및 전극막에 대한 적당한 이형성과 밀착성을 가짐과 함께, 접착 용이층 등의 접착층을 개재시키지 않고, 범용의 기재 필름에 밀착할 수 있기 때문에, 고체 고분자형 연료 전지의 막 전극 접합체를 제조하기 위한 이형 필름에 적합하다. A polymer film comprises a polymer composition containing (A) a cyclic olefin polymer containing an olefin unit having a C 3-10 alkyl group as a side chain thereof and (B) a chlorine-containing polymer. The chlorine-containing polymer (B) may comprise a vinylidene chloride-series polymer. The ratio of the chlorine-containing polymer (B) relative to 100 parts by weight of the cyclic olefin polymer (A) may be 0.5 to 60 parts by weight. The film has a moderate releasability from an electrolyte membrane and an electrode membrane of a polymer electrolyte fuel cell and a moderate adhesion to the electrolyte membrane and the electrode membrane and can adhere to a commonly-used substrate film without interposition of an adhesive layer such as an easily adhesive layer. The film is thus suitable as a release film for producing a membrane electrode assembly of a polymer electrolyte fuel cell.
