摘要
Abstract
In the experiment, poly-vinyl-chloride (PVC) and poly-vinyl-butyral (PVB) were blended to prepare the PVC ultra-filtration (UF) membrane. To show the compatibility of the system as a partly miscibility system, the compatibility of the PVC/PVB blending system was characterized by dilute -solution viscosity (DSV), dynamic viscosity method and visual method. To further systematically study the blending miscibility of the polymer PVC and PVB in the dilution di -methyl -acetamaide (DMAc), the characteristics of PVC/PVB casting solution and the ultra-filtration membrane prepared by non-solvent induced phase separation (NIPS) in different concentration of polymers, as well as in different ratio of PVC and PVB, was tested. Concentration and ratio of the polymer was also discussed to explore the influence to the structure and its miscibility of separation of the blending ultra-filtration membrane, which provides theory basis for the preparation of ultra-filtration membrane that using PVB to blend modified PVC as material.关键词
