Investigation of the stability of a mixture of single-based propellants and resins or polymers.
The stabilisation of single-based propellants (SBP) with equal quantities of bisphenol A-based epoxy resin (ER), bromine-containing epoxy resin (BER), chlorinated polyvinylchloride (PCV) and chlorinated rubber (CR) were investigated by viscosimetry and calorimetry. All compounds were thermodynamically compatible with SBP. The degree of stabilisation of SBP was measured after accelerated ageing and was evaluated by the loss of weight and by means of differential scanning calorimetry (DSC). All compounds produced a significant decrease in the loss of weight, typically by more than a factor of 15 compared with unstabilised SBP. The stability of the compounds decreased in the order: CR>BER>PCV>ER.
