Abstract

본 발명은 고분자 필름의 제조 방법에 관한 것이다. 60중량% 이상이 스티렌 단량체로 이루어진 스티렌계 수지 및 산가 1.0mgKOH/g 이하의 설폰산 금속염 유도체를 가지고 있는 폴리에스테르 수지를 함유하고 고분자 수지 쉬트를 제조하는 단계 ; 상기 단계에서 얻어진 고분자 쉬트를 종연신하는 단계 ; 및 상기 단계에서 종연신된 필름을 하기의 조건으로 횡연신한 다음, 열처리하는 단계를 포함하여 제조된 고분자 필름은 겉보기 밀도, 표면저항, 파단강도, 열수축율 등의 물성이 우수하다. 또한 그 공정성면에서도 우수하여 파단의 발생빈도가 크게 줄어들었다.The present invention relates to a method for producing a polymer film. Preparing a polymer resin sheet containing at least 60% by weight of a styrene resin comprising a styrene monomer and a polyester resin having a sulfonic acid metal salt derivative having an acid value of 1.0 mgKOH / g or less; Longitudinal stretching the polymer sheet obtained in the step; And the polymer film produced by stretching the film longitudinally stretched in the above conditions under the following conditions, and then heat treatment is excellent in physical properties such as apparent density, surface resistance, breaking strength, heat shrinkage. In addition, it is excellent in the fairness, the frequency of breakage was greatly reduced.
