Investigation of the Compatibility of a Novel Copolymer Base

28/12/2020 · Abstract Plasticizers were added to the polymeric networks to improve the performance of the composite solid propellants. Energetic plasticizers were used to increase the energy content, in addition to improving the glass transition temperature and mechanical properties. The compatibility between polymer and plasticizer is an important criterion for obtaining the best thermomechanical Designing a Highly Energetic PCL-GAP-PCL-based PU Elastomer; Energetic plasticizers contribute to the combustion mechanics by increasing the overall enthalpy [17, 18]. Therefore, to improve the performance and specific impulse of solid propellants a plasticizer should be added. Nitrate esters are important plasticizers in
