Hydroxyl terminated polybutadiene (HTPB) is a low molecular weight polymer which has used in various industries. The good mechanical and thermal properties of HTPB based polyurethane is caused to use it as a binder for the solid composite propellants and plastic bonded explosives. Also, The presence of double bonds and hydroxyl end groups in the structure of HTPB can provide an opportunity to improve its properties through chemical modification by various reactant and develop its application. In this paper, we classify and study the chemical modification of HTPB under the basis of the reactions were carried out on the carbon-carbon double bond, terminal hydroxyl group and terminal carbon atoms of hydroxyl terminated polybutadiene.
