Abstract
Poly(phenyl sulfone) (PPSU), composed of repeating aryl ether (Ar-O-Ar) and sulfone (-SO2-) units, exhibits excellent thermal stability and mechanical strength, attributed to the high polarity of the sulfone groups, as well as strong resistance to chemicals, UV radiation, and hydrolysis. These characteristics allow the PPSU to withstand high-temperature and high-pressure environments. In this study, photocurable methacrylate-terminated poly(phenyl sulfone) (MAPPSU) was synthesized via etherification of dichlorodiphenyl sulfone (DCDPS) and 4,4-dihydroxybiphenyl (DHBP) using potassium carbonate as the catalyst, followed by the reaction with methacryloyl chloride (MAC) using triethylamine (TEA) as an esterification catalyst to introduce methacrylate end groups. The formation of MAPPSU was confirmed through FT-IR, 1H-NMR, GPC, TGA and DSC analyses, and used to formulate dental resin via DLP 3D printer to evaluate its mechanical properties much as compressive and flexural strengths.
