Abstract
Normally water insoluble hot melt adhesive compositions containing structural polymers such as A-B-A block copolymers, butyl rubbers, polyesters, ethylene vinyl acetates, ethylene acrylic acid polymers can be made sensitive to the action of water using an effective water sensitizing amount of a polyalkyloxazoline polymer in the hot melt adhesive. The polyalkyloxazoline polymer can be incorporated into a single phase adhesive composition with the structural polymer using an effective amount of a hydroxyl or carboxylic acid compound.
