Abstract: Uv-curable acrylpimaric acid polyurethane acrylate(APAPUA) oligomer for coatings was prepared from 2, 4-toluene diisocyanate(TDI), acrylpimaric acid diglycol polyester diol and hydroxypropyl acrylate(HPA). Its structure was characterized using IR. The UV curing behavior of APAPUA was investigated. The hardness, flexibility and other mechanical properties of the cured APAPUA film were tested and its thermal stability was also studied, confirming that this cured APAPUA film has superior properties in mechanical properties and heat resistance.

Key words: acrylpimaric acid; polyurethane acrylate; UV curable; mechanical property; heat resistance
