CLEMENTE, Marcelo; ROCHA, Roberta J.; IHA, Koshun  and  ROCCO, José A. F. F.. Development of prepolymer technology in the synthesis of a polyurethane binder used in solid rocket fuels. Quím. Nova [online]. 2014, vol.37, n.6, pp.982-988. ISSN 0100-4042.

The aim of this work was to synthesize a polyurethane polymer matrix using polyols as a raw material to obtain a binder such as the hydroxyl terminated polybutadiene (HTPB) pre-polymer in energetic material formulation. The soybean-based polyol was the best starting raw material for producing a binder for solid fuel formulation in rocket motor applications. Characterization of the obtained soybean-based polyurethane binder was carried out by employing FT-IR analysis and thermo analytical techniques that showed similar HTPB binder thermo decomposition behaviors, confirming their potential for use as polymer matrix composites.

Keywords : hydroxyl terminated polybutadiene; soybean-based polyol; energetic materials.
