Claims (3)

이산 성분으로는 방향족 디카본산 장기와 세바신산 잔기로 구성되고, 디올 성분으로는 에틸렌글리콜 잔기와 네오펜틸글리콜 잔기로 구성되는 공중합 폴리에스테르를 제조함에 있어서, 하기 일반식(1)로 표시되는 유기주석 화합물을 반응촉매로 전산성분에 대해 0.005내지 0.5중량부 첨가 사용하는 것을 특징으로한 공중합 폴리에스테르의 제조 방법.The diacid component is composed of an aromatic dicarboxylic acid organ and a sebacic acid residue, and the diol component is an organotin represented by the following general formula (1) in preparing a copolyester composed of an ethylene glycol residue and a neopentyl glycol residue. A method for producing a copolyester characterized in that the compound is used in an amount of 0.005 to 0.5 parts by weight based on the total amount of the compound as a reaction catalyst. 상기에서 R1은 알킬기 또는 아릴기; X1,X2,X3는 같거나 서로 다를수 있으며 알킬기, 알릴기, 시클로알킬기, 아실옥실기, 히드록실기 또는 할로겐등의 1가의 기이며; Y는 S원자 또는 O원자이다.R 1 is an alkyl group or an aryl group; X 1, X 2, X 3 may be the same or different and are a monovalent group such as an alkyl group, an allyl group, a cycloalkyl group, an acyloxyl group, a hydroxyl group or a halogen; Y is S atom or O atom. 제1항에 있어서, 공중합 폴리에스테르를 구성하는 성분인 방향족 디카본산잔기가 테레프탈산 또는/및 이소프탈산을 원료로 사용하여 구성되고, 세바신산 잔기는 세바신산을 원료로 사용하여 구성되는 것을 특징으로한 방법.The aromatic dicarboxylic acid residue as a component constituting the copolyester is composed of terephthalic acid and / or isophthalic acid as a raw material, and the sebacic acid residue is composed of sebacic acid as a raw material. Way. 제1항에 있어서, 전이산성분 투입량 1몰부에 대하여 전디올성분 투입량을 1.5몰부 이하로 하는 것을 특징으로한 방법.The method according to claim 1, wherein the total diol component amount is set to 1.5 mol parts or less with respect to 1 mol part of the transition acid component amount. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
