Abstract

Poly aryl ether ketones (PAEKs) has now gradually become the leading polymer material in the fields of biomedical polymer, due to its good biocompatibility and high thermal, mechanical properties. Among PAEKs, PEKK has advantages such as higher thermal stability, better mechanical properties, versatile chemistry due to two ketone bonds compared to other PAEKs. We focused on poly(ether ketone ketone) based oligomer to improve the mechanical properties of dental resin. In this study, HEMA-terminated poly(ether ketone ketone) oligomer (CAEKK-HEMA) was synthesized using carboxylic acid-terminated poly(ether ketone ketone) oligomer(CA-EKK) and 2-Hydroxyethyl methacrylate(HEMA) and characterized by FT-IR, ¹H-NMR, and GPC. To investigate mechanical properties, the mixture of CAEKK-HEMA and ethoxylated bis-GMA(EBPDMA) with various ratios were photopolymerized by DLP 3D printer and their mechanical properties such as compressive and flexural strength were measured.
