Method of adhesive bonding by use of thermotropic liquid crystal polymers

摘要

An improved method of bonding a polymeric composition comprised of a thermotropic liquid crystalline polymer to a substrate is provided. It has been determined that the adhesion of a thermotropic liquid crystalline polymer to a substrate is enhanced if the absolute difference between the surface pH of the substrate to which the polymer is to be bonded and the pH of the polymer itself is at least approximately 1.0 pH unit as measured by the method described herein.
