Abstract: PURPOSE: A method for preparing polyisoimide is provided, to improve the mechanical properties, the heat stability, the electric insulation property, the flame retardancy and the chemical resistance by preventing the gelation generated during the cyclodehydration. CONSTITUTION: The method comprises the steps of polymerizing a dianhydride monomer and a diamine monomer; and preparing the polyisoimide from the polymer by the cyclodehydration in the presence of an end-capper selected from an acid chloride and a chloroalkylsilane at a low temperature of -30 to 10 deg.C. Preferably the acid chloride is selected from the group consisting of acetyl chloride, benzoic chloride, propanoic chloride and p-toluenesulfonyl chloride; and the chloroalkylsilane is chlorotrimethylsilane or chlorotriethylsilane. The amount of the end-capper is 0.01-0.2 mol based on 1 mol of the diamine monomer.

Abstract: 본 발명은 액상 자외선 차단제에 관한 것으로서, 더욱 상세하게는 벤조페논계 화합물 및 벤조트리아졸계 화합물 중에서 선택된 단종 또는 2 종 이상을 치환기로 갖는 실리콘 폴리머 화합물을 포함하는 자외선 차단제에 관한 것이다. 본 발명의 액상 자외선 차단제는 유기용제, 고분자 재료에 대한 상용성이 우수할 뿐만 아니라, 본 발명은 액상이기 때문에 화장품용 자외선 차단제 제조시 계면활성제를 대량 첨가로 발생하는 문제가 없는 장점이 있으며, UV-A선 및 UV-B선을 골고루 흡수할 수 있기 때문에 자외선 차단 효과가 우수하다.
