Adhesion between Polystyrene and Polymethylmethacrylate.

Abstract

Measurements have been made of the energy required to break through unit area of polystyrene (PS), polymethylmethacrylate (PMMA), and joints prepared by molding the two polymers in contact. The interface was significantly weaker than either adherend, but surprisingly strong for two incompatible materials. Microscopy and selective dyeing revealed that fracture took place at the interface itself, with no appreciable transfer of material from one side to the other. It is concluded that van der Waals interactions are sufficient to create relatively strong bonds. Keywords: Adhesion, Fracture, Polymer interfaces, Polymethylmethacrylate, Polystyrene.
