제목 Preparation and Characterization of Cross-linked Polysulfone Film for Chemical-Resistance via Chloromethylation Method using Methacrylic Acid
초록 Polysulfone (PSf) is amorphous polymer which possesses excellent thermal stability and good optical properties1. But it has drawbacks such as poor chemical resistance and gas barrier property.
In this work, we introduced crosslinkable moiety using chloromethylation method for the modification of polysulfone which could be overcome above shortcomings for display plate based on plastic film. We prepared photosensitive polysulfone having methacrylic acid moiety2 from chloromethylated polysulfone (CMPSf). It was confirmed that the reaction was almost quantitatively from the 1H-NMR spectra (Fig. 1.). The thermal, mechanical and gas barrier properties were measured by TGA, DSC, UTM and MOCON test method (Permatran W3/31). DSC analysis of polysulfone methylene methacrylate (PSfMM) was showed in improving thermal behaviors than that of PSf (Fig. 2.).
