| Abstract | Acrylic copolymers made of a casting syrup (prepared from poly(methyl methacrylate) (PMMA) dissolved in methyl methacrylate) and triethylene glycol dimethacrylate (TEGDMA) were synthesized by promoting the decomposition of benzoyl peroxide (BP) with dimethyl-p-toluidine. In addition, conventional copolymers, made of methyl methacrylate and triethylene glycol dimethacrylate monomers, were synthesized via thermal decomposition of BP. The two types of reaction were carried out as bulk polymerizations. Both types of copolymers were studied applying scanning electron microscopy, IR and micro-Raman spectroscopy, differential scanning calorimetry, and dilatometry. It was found that the conventional polymer is a MMA-TEGDMA copolymer without phase separation, while the phase-separated polymer contains microdomains. The shrinkage of the polymers, as well as their morphology, can be easily controlled through the chemical composition. |
