Polyether (meth)acrylates based on cyanuric acid or substituted cyanuric acid and multifunctional alcohol, which optionally include triethanolamine units, have wide applications in UV curable adhesives, coatings, inks, sealants, paints or 3D printing. These polyether acrylates have rigid cyanurate structure endowing the material with extra strength and thermal stability. Furthermore, triethanolamine unit, when present, endows the material with anti-oxygen inhibition property in UV curing process. These polyether (meth)acrylates have low viscosity and high reactivity towards UV curing. The cured resins have high resilience and strength. The process of making the polyether (meth)acrylates includes the synthesis of trifunctional polyether polyols through controlled polymerization of propylene oxide using multifunctional alcohol (such as glycerol and sucrose), cyanuric acid or substituted cyanuric acid, and optionally triethanolamine, in the presence of a catalyst, followed by the synthesis of polyether (meth)acrylates through transesterification or through direct esterification of the trifunctional polyether polyols.
