Table 3.

Summary of DMA data (T g: glass transition temperature determined from the maximum of tanδ, E′: storage modulus obtained 40 K above T g where the system can be seen as relaxed) obtained after exposure of 2 min at 395 nm and 10 min at 805 nm with a radiation source emitting either 395 nm (1.1 W cm−2) or 805 nm (1.2 W cm−2) while the conversion degree at this time x was determined for the monomer polymerizing according to a cationic polymerization mechanism (cat) and/or radical polymerization mechanism. Thickness of the films was 120 μm.
