Synthesis of high-solid, low-viscosity hydroxy acrylic resin modified with TBCHA

Abstract

Hydroxyl acrylic resin using 4-tert-Butylcyclohexyl acrylate (TBCHA) as functional monomer has been synthesized via solution polymerization technique. Most critical experimental conditions have been optimized first by mixture experimental design methodology prior to real experiment operations. Afterward high-solid and low-viscosity hydroxy acrylic resin was synthesized under the optimized experimental conditions. According to a series of characterization methods including rheology, IR, TGA, addition of functional monomer, TBCHA, combined with optimized experiment conditions can reduce the viscosity of as-synthesized resin significantly at high solid content.
