ABSTRACT

Selection of an Adhesive 137

Very recently, Wielinski (1382) reported on investigations to formulate hot-melts with more heat and oil resistance. Copolymerization of ethylene with vinyl acetate (VA) to produce ethylene vinyl acetate (EVA) resins was the basis for a variety of hot-melt systems but more heat and oil resistance was often desired. These important property improvements have been gained by substituting n-butyl acrylate (nBA) for the VA. These resins now constitute a new family of ethylene copolymers for compounding hot-melts. Improvements in heat stability, low-temperature flexibility, and oil resistance are significant.
