Synthesis and Characterization of AN/HEA Copolymer and AN/MA/HEA Terpolymer(Ⅰ)

Neutral polymeric bonding agent(NPBA)s have been developed as a new kind of bonding agent for the propellants in which RDX particles are dispersed in a PEG binder matrix containing highly energetic nitratoester plasticizers. Terpolymers with 64 : 27 : 9 mol% and 67 : 20 : 13 mol% composition of acrylonitrile(AN), methylacrylate (MA), and 2-hydroxyethylacrylate(HEA), and copolymer with 83 : 17 mol% composition of AN and HEA were synthesized with AIBN as initiator by radical polymerization in acetone at 60℃ as NPBA. Compositions and OH indices of the NPBA were determined by elemental analysis and ¹H-NMR. The monomer reactivity ratios, r₁(AN) and r₂(HEA) were determined by the Kelen-T d s method , r₁=1.13, r₂=0.65. The average molecular weights of NPBAS were controlled in the range of 20,000∼60,000 g/mol by the concentration of initiator and/or chain transfer agent.
