Part I of the study tested how differences in the curing wavelength, as well as exposure to UV light during the polymerization process, affected the Tg. Part II tested the differences in the polymer characteristics when casted compared with when spin-coated. Part III examined how monomer mole variations affect Tg, the degradation process, and water uptake. Samples 3A and 3B were not tested against each other, but against themselves.
