Use of glycidyl methacrylate monomers for developing crosslinkable pressure sensitive adhesives

Emulsion copolymers based on glycidyl methacrylate and butylacrylate (or 2- ethylhexylacrylate) were prepared and evaluated as pressure sensitive adhes ives. These emulsions were characterised by their non-volatile content, vis cosity, mechanical stability, swelling behaviour, IR spectroscopy, differen tial scanning calorimetry and scanning electron microscopy. The pressure se nsitive adhesive rapes were prepared with flexible backings and the peel st rengths between flexible flexible and flexible-rigid surfaces were determin ed. The swelling propel ties of these copolymers before and after curing we re also studied. (C) 2000 Elsevier Science Ltd. All rights reserved.
