Synthesis and application of cis-butenedioic anhydride modified epoxy dimethacrylate resin / 医疗卫生装备

This study aims to synthesize cis-butenedioic anhydride modified epoxy dimethacrylate resin and evaluate their physico-mechamical properties.Stoichiometric amounts of E51 type epoxy resin,methacrylate acid and cis-butenedioic anhydride were reacted with N,N-dimethylbenzylamine as a catalyst.The compressive strength,diametral tensile strength,surface hardness,cured depth,water uptake,and water solution of the composite resin with EAM monomers and those of EMA were measured.The composite resin with EAM monomers gave high value of compressive strength,diametral tensile strength,surface hardness and lower water uptake and water solution compared to EMA monomers.
