摘要

Fourier transform infrared spectroscopy (FTIR) and the fluorescence probetechnique were used to study photochemically made interpenetrating polymer networks (IFN) made of acrylated monomers and an unsaturated polyester oligomer. The acrylated monomers were polyol acrylates and the UPE was based on maleic anhydride and propylene glycol with styrene as the solvent and cross-linking agent. The acrylate band at 810/cm was used for the acrylates while the bands at 982 and 1640/cm were used for the UPE. The fluorescence probe used was 5-dimethylaminonaphthalene-1 sulfonyl-n-butylamide DASB. These spectroscopic techniques monitored processes that took place right after the irradiation and
