Resinification of FA with MMT Clay

To provide a basis for comparison with PFA modified with CW and MMT, PFA resin without CW or MMT was prepared using 3phr y-alumina (nanopowder, Aldrich) as a catalyst. The resin obtained after reaction at 100 °C for 12 h (denoted y-Al-PFA) was stable during storage (at room temperature) for several months. 

To characterize the curing behavior and to investigate how the presence of MMT influences the polymerization of FA, FTIR, and DSC, spectra were collected before and during the resinification process.
