The present invention relates to a polyester polymerization composition which further improves dispersibility of silica particles and reduces the content of aggregated particles, a polyester resin master batch chip, and a polyester film using the same. The polyester polymerization composition comprises a monomer composition including a diol component and a dicarboxylic acid component or a prepolymer composition of the monomer composition, and a silica slurry composition. 본 발명은 실리카 입자, 더욱 좋게는 실리카 미립자의 분산성을 더욱 향상시키고 응집입자의 함량을 감소시킨 폴리에스테르 중합 조성물, 폴리에스테르 수지 마스터배치 칩 및 이를 이용한 폴리에스테르 필름에 관한 발명이다.
