Abstract: (2762 Views)

Binder has a key role in the performance of composite propellants. The binders are classified into two neutral and high-energy categories. GAP is one of the most important energetic binders, but it has poor mechanical and thermal properties. The goal of this investigation is to improve the properties of GAP by copolymerizing it with polycaprolactone. New energy triblock copolymer was synthesized using a glycidyl azide polymer (GAP) as a macroinitiator and cation ring polymerization method using caprolactone monomer in the presence of dibutyltin dilaurate as a catalyst, And the synthesis method was optimized. The triblock copolymer w:as char:acterized using GPC, ¹³CNMR, ^ˡHNMR, IR. The thermal behavior of the synthesized polymer has been investigated using DSC-TGA, which results showed increasing the thermal stability and reducing the glass transition of the copolymer compared to GAP.

Keywords: copolymer, binder, glycidyl azide polymer, polycaprolactone
