Abstract
Non-toxic tertiary amines having very low vapor pressures and substantially insolubility in water and fats are employed as free radical catalyst activators for adhesive compositions comprising polyurethane polymers or elastomers dissolved in an addition polymerizable combination of an acrylic or methacrylic monomer, a copolymerizable monomer containing a free carboxylic acid group and a non-activated free radical polymerization catalyst.
