Abstract : This invention pertains to a solid rocket propellant grain which contains hydroxyl terminated polybutadiene and is bonded to a rocket motor liner which contains carboxy terminated polybutadiene. This is done by carrying out the following sequence of steps: First, the liner is cast and cured; then the liner is coated with a solution of a bromine terminated phenol-formaldehyde copolymer which uses normal hexane as the solvent; next, the coat is allowed to dry for from about 15 to about 30 minutes; finally, the propellant grain is cast and cured.
