Abstract
Phenoxyresin (PX) known as a plastic resin with dimension consistency was esterificated with glycidyl acrylate (GA) and glycidyl methacrylate (GM). Thus the photosensitive polymers, PXGA with acryloyloxy group and PXGYI with methacryloyloxy group, were synthesized . PXGA is not investigated as a photopolymer until now, but PXGM is a commercial product. In this report PXGM was synthesized for the purpose of comparing with PXGA in the photosensitivity. The rates of reaction of PX with GA and GM were almost the same each other under the same synthesizing conditions. PXGA was synthesized in the presence of anti-thermal polymerization reagent, hydroquinone (HQ), though PXGM was done without HQ. PXGA was more photosensitive than PXGM according to grayscale method. The dynamic viscoelastic properties were measured about PX, PXGA, PXGA composite with some additives (PXGA') and PXGA' irradiated by UV lamp (PXGA"). The elasticity of PX was decreased with accepting the photosensitive group and receiving the additives.
