Abstract

Two kinds of polyurethanes with β-cyclodextrin and amino-β-cyclodextrin were synthesized in one step procedure. Their structure was determined by FTIR spectroscopy. Thermal stability and swelling behavior were evaluated. Amino-βcyclodextrin-polyurethane has higher thermal stability then β-cyclodextrin-polyurethane. The swelling degree of βcyclodextrin product is higher comparing with amino polyurethane, but it is also the subject of the hydrolytic reactions which influence the ability for scavenging. The scavenging properties were studied by static headspace chromatography. In order to prevent environmental pollution, cyclodextrin-polyurethanes can be used as scavenging materials for contaminated solution or atmosphere. This study shows the effectiveness of cyclodextrin-polyurethanes in trapping pollutants..
