- 교반기, 분류콘덴서, 가스도입관, 온도계 등이 부착된 반응장치에 지방족(환상 지방족을 포함함) 디카르복실산(또는 그의 산무수물)과 지방족(환상 지방족을 포함함) 글리콜을 1:1∼1:1.8의 몰비로 첨가하고, 상기 디카르복실산과 상기 글리콜의 중합반응에 의하여 생성되는 폴리에스테르의 이론량 100중량%에 대해 무기물을 5∼60중량%를 직접 첨가하여 질소기류 중에서 교반하면서 에스테르화 반응시키는 단계와, 상기 에스테르화 반응이 완료되면 에스테르화 반응생성물을 계속적으로 교반하면서 상기 반응장치에 중축합 반응촉매를 첨가한 후 중축합 반응기로 이송하는 단계와, 상기 중축합 반응기로 이송된 에스테르와 반응생성물을 1.5∼0.1Torr의 고진공하에서 230∼260℃의 온도로 2∼5시간동안 탈글리콜 반응시킴으로써 고분자량화하는 단계로 구성됨을 특징으로 하는 폴리에스테르 복합수지의 제조방법.
- 제1항에 있어서, 상기 무기물로서 톱밥, 탈크, 탄산칼슘, 이산화티탄, 산화마그네슘, 황산마그네슘 중 선택된 어느 하나 또는 둘 이상의 혼합물이 사용됨을 특징으로 폴리에스테르 복합수지의 제조방법.
- (1)지방족(환상 지방족을 포함함) 디카르복실산(또는 그의 산무수물)과 (2)지방족(환상 지방족을 포함함) 글리콜을 주성분으로 하여, 상기 디카르복실산과 상기 글리콜의 중합반응에 의하여 생성되는 폴리에스테르의 이론량 100중량%에 대해 (3)무기물 5∼60중량%을 첨가하고, 상기 성분들을 에스테르화 반응 및 탈글리콜 반응시켜서 얻어진 폴리에스테르 복합수지의 신율이 5∼500%이고, 인장강도가 250∼500kg/cm2임을 특징으로 하는 폴리에스테르 복합수지 조성물.
- 제3항에 있어서, 상기 무기물로서 톱밥, 탈크, 탄산칼슘, 이산화티탄, 산화마그네슘, 황산마그네슘 중 선택된 어느 하나 또는 둘 이상의 혼합물이 이용됨을 특징으로 폴리에스테르 복합수지 조성물.
