Grafting of cyclodextrins onto polypropylene nonwoven fabrics for the manufacture of reactive filters. I. Synthesis parameters

摘要

A novel method for the preparation of immobilized alpha-, beta-, and gamma-cyclodextrins (alpha-, beta-, or gamma-CD) on polypropylene (PP) nonwoven fabrics is presented. These new materials were prepared by graft-polymerization of glycidyl methacrylate (GMA) onto PP filters using the electron-beam technique, followed by coupling of alpha-, beta-, and gamma-CDs with the epoxide group. Optimization of various reaction parameters such as time, temperature, irradiation dose, monomer, and CD concentration was carried out. (C) 2000 John Wiley & Sons, Inc. [References: 33]
