Abstract
본 발명은 석신산, 석신산무수화물 또는 석신산에스테르화합물 중에서 선택된 1성분과 1,4-부탄디올을 주성분으로 하고, 결정거동 조절을 위한 모노머로서, 1,4-사이클로헥산디메탄올 또는 2,2-디메틸-1,3-프로판디올에서 선택된 1종 또는 그들의 혼합물을 석신산, 석신산무수화물 또는 석신산에스테르화합물 중에서 선택된 1성분에 대하여 1∼30몰%, 3관능이상의 다관능성을 갖는 화합물을 석신산, 석신산무수화물 또는 석신산에스테르화합물 중에서 선택된 1성분에 대하여 0.01∼1몰%의 비율로 첨가하여 220℃ 이하의 온도에서 에스테르화 또는 에스테르 교환반응시킨 후, 콘덴서 및 교반기가 부착된 반응기에 에스테르화 또는 에스테르 교환반응 생성물을 투입하고 열안정제, 촉매 및 기타 조제를 첨가하여 1mmHg 이하의 고진공하에서 240∼260℃의 온도로 축중 반응시켜 공중합 폴리에스터를 제조한후, 탄산칼슘을 포함한 최소 2성분으로 혼합된 무기 충진제 혼합물을 제조된 수지에 대하여 5∼60중량% 첨가하여 120∼160℃로 용융 블랜드하는 지방족 폴리에스터의 제조방법에 관한 것이다.The present invention mainly comprises one component selected from succinic acid, succinic anhydride or succinic acid ester compound and 1,4-butanediol, and as a monomer for controlling crystal behavior, 1,4-cyclohexanedimethanol or 2,2 A compound having 1 to 30 mole% and trifunctional or higher polyfunctionality with respect to one component selected from dimethyl succinic acid, succinic anhydride or succinic acid ester compound 0.01 to 1 mol% of succinic acid, succinic anhydride or succinic acid ester compound is added at a rate of 0.01 to 1 mol%, and esterified or transesterified at a temperature of 220 ° C. or lower, followed by a reactor equipped with a condenser and a stirrer. The esterification or transesterification product was added to the mixture, and a heat stabilizer, a catalyst, and other preparations were added, and stored at a temperature of 240 to 260 ° C. under a high vacuum of 1 mmHg or less. After the reaction to prepare a copolyester, a method of producing an aliphatic polyester melt blended at 120 to 160 ℃ by adding 5 to 60% by weight of the inorganic filler mixture mixed with at least two components including calcium carbonate to the prepared resin It is about.
