THE EFFECT OF TRIACRYLATE MONOMER STRUCTURE ON VOLUME SHRINKAGE AND TENSILE PROPERTIES OF VAT POLYMERIZATION RESINS

This study investigates the influence of triacrylate monomer structure on volume shrinkage, tensile properties, and viscosity vat polymerization (VP) resins. The amount kept constant as 20%wt. to prevent excessive shrinkage effect. Results indicated that ethoxylated propoxylated structures are beneficial reduce VP However, these flexible chain led a reduction in properties elastic modulus resins deteriorated up 35% compared trimethylolpropane (TMPTA). There is no significant effect observed resin reactivity according type. Besides, presented best dilution resin.
