Zusammenfassung:	The present invention relates to a method for predicting the quality of a polymer, which comprises the steps of: (S1) measuring molecular weight distribution of a polymer and the number distribution of short chain branches; (S2) calculating the average value and deviation of crystallogenesis units of the polymer from the measured molecular weight distribution and number distribution of short chain branches; and (S3) calculating a predicted internal pressure value from the average value and deviation of the crystallogenesis units of the polymer. 본 발명의 고분자의 분자량 분포 및 짧은 사슬 가지의 개수 분포를 측정하는 단계(S1), 상기 측정된 고분자의 분자량 분포 및 짧은 사슬 가지의 개수 분포로부터 상기 고분자의 결정생성단위의 평균값 및 편차를 계산하는 단계(S2) 및 상기 고분자의 결정생성단위의 평균값 및 편차로부터 내압 예측 값을 계산하는 단계(S3)를 포함하는 고분자 품질 예측 방법에 관한 것이다.
