Multilayer films from uncompatible polymers polymethylmetacrilate
polystyrene have
poor adhesion and interlayer strength. Application of copolymers enhances adhesion be-
tween layers and delaminating strength. Intersection of layers as a result of irregular
morphology also improves delamination strength. For test of multilayer films with poor
interlayer strength the torsion technique is recommended. Frictional microscopy of de-
laminated surfaces reveals mechanism of interlayer bond in films.
Keywords:
polymers, films, adhesion, frictional microscopy.
