Selectively permeable membrane and preparation thereof |
| abstract |
PURPOSE: To disclose polyester and polyamide membranes having improved permeation properties. n CONSTITUTION: The membranes are derived from t-butyl-substituted isophthaloyl halide, in particular, 5-t-butylisophthaloyl chloride. The t-butyl-substituted isophthaloyl chloride can be employed with monomers such as diols and diamines to provide polyesters and polyamides with improved permeation properties. n COPYRIGHT: (C)1992,JPO |
