摘要：
The photooxidative behaviour of a new kind of hybrid system based on silanised poly(ether-urethane)s (SPURS) has been analyzed by Fourier transform infrared spectroscopy (FTIR) and atomic force microscopy (AFM). The influence of polyether molecular weight and SPUR chemical nature as well as the addition of HALS and UVA stabilizers on the system photodegradation has been studied. FTIR results and AFM images have shown that the light stabilizers considerably enhance the photodegradation resistance, specially the HALS type stabilizer. (C) 2007 Elsevier Ltd. All rights reserved.
