Abstract
An elastomeric or rigid polymeric material, such as a propellant, is strongly bonded to an incompatible material, such as a silicon rubber liner, when a long chain polymer which is insoluble in and unreactive with the liner but has groups reactive with the propellant is added to the liquid or uncured liner. As the liner cures, the polymer chain migrates to the surface. Upon laying the propellant on the surface and curing the propellant, the propellant is cross-linked to the long chain polymer, which is entangled in the rubber liner.
