The present invention relates to: a dispersant for a non-aqueous electrolyte battery separator, including a cyanoethyl group-containing polymer; a non-aqueous electrolyte battery separator using the same; and a non-aqueous electrolyte battery. Further, the present invention relates to a method for producing the cyanoethyl group-containing polymer. A dispersant composition for the non-aqueous electrolyte battery separator comprises the cyanoethyl group-containing polymer including a first repeating unit represented by chemical formula 1, a second repeating unit represented by chemical formula 2, and a third repeating unit represented by chemical formula 3. A separator composition for the non-aqueous electrolyte battery of the present invention can further improve the heat resistance of the separator. 본 발명은 시아노에틸 기 함유 중합체를 포함하는 비수전해질 전지 세퍼레이터용 분산제, 이를 사용한 비수전해질 전지 세퍼레이터, 및 비수전해질 전지에 관한 것이다. 또한, 본 발명은, 시아노에틸 기 함유 중합체의 제조 방법에 관한 것이다.
