Abstract:
본 발명은 나노브러쉬형 친환경 대체가소제 화합물 및 단일반응기 공정(one-pot process)을 이용한 이의 제조방법에 관한 것이다. 본 발명에 따른 나노브러쉬형 친환경 대체가소제는 내분비계 장애물질인 프탈레이트 화합물 배제를 위해 환경 및 체내에 무해한 코어물질에 환경친환성 및 생체적합성을 지닌 락톤계 단량체를 브러쉬물질로 개환중합 시키고, 최종적으로 브러쉬의 말단 수산기를 안정화한 화합물이다. 이러한 나노브러쉬형 친환경 대체가소제는 폴리염화비닐(PVC)과 우수한 혼화성 및 PVC 외부로의 유출이 없어, 우수한 가소화 효과를 부여하는 동시에 환경호르몬 문제 및 환경규제에 대응할 수 있다. 또한, 본 발명에 따른 나노브러쉬형 친환경 대체가소제의 제조방법은 유기용매를 사용하지 않고 단일반응기 공정으로, 경제성과 상업성 및 친환경성을 지닌 나노브러쉬형 친환경 대체가소제 제조가 가능하다.

Abstract:
PURPOSE: An environment-friendly nanobrush-type alternative plasticizer is provided to cope with environment regulations while providing excellent plasticizing effects because of excellent miscibility with PVC while preventing a leakage of PVC to outside. CONSTITUTION: An environment-friendly nanobrush-type alternative plasticizer is in chemical formula 1. In chemical formula 1, A is a moiety excluding -OH from a polyol selected from linear aliphatic polyol, cyclic aliphatic polyol, oxygen-containing linear aliphatic polyol, and oxygen containing cyclic aliphatic polyol, R is hydrogen or CaHbOcNdPe, R' is C1-10 alkyl, and C6-20 aryl or C3-10 cycloalkyl, w is 0 or 1, x is an integer from 1 or more, y is an integer form 1 or more, z is, as a number of -OH in polyol of A, an integer from 2 or more.
Abstract:
PURPOSE: A metallic ion absorbing membrane and a method for manufacturing the same are provided to reuse the metallic ion absorbing membrane by eliminating metallic ions from the membrane. CONSTITUTION: A composition for a metallic ion absorbing membrane is applied and is introduced into a hydrophilic coagulating solution. Amphiphillic dendritic polymer is self-assembled on the surface of the metallic ion absorbing membrane in order to absorb heavy metallic ions from the solution. The heavy metallic ions are acid-based adjusted to be cleaned. The composition includes polymer for forming a membrane, dendritic polymer, an organic solvent, and an additive. The polymer for forming the membrane is selected from a group including polysulfone, polyimide, polyamide imide, polyamide, polyacrylonitrile, and polyvinylidene fluoride.
