PURPOSE: To obtain a heat-stable hot melt adhesive which can be used for bonding various adherends by mixing a specified ethylene terpolymer with a tackifier.
CONSTITUTION: A hot melt adhesive composition which is a molten liquid at a service temperature and comprises an ethylene terpolymer comprising about 40-87wt.% ethylene, about 5-50wt.% second monomer selected between an alkyl acrylate and an alkyl vinyl ether (wherein the alkyl has 1-8C atoms) and about 3-30wt.% third monomer selected between carbon monoxide and sulfur dioxide (based on the weight of the terpolymer), about 5-80wt.% compatible tackifier (based on the total weight of the terpolymer and the tackifier) and 0-30wt. % compatible plasticizer (about 4wt.% or below when the second monomer is present in an amount of 10wt.% or below).
