The knowledge of polymer network characteristics is important to tune the properties of advanced energetic propellants based on nitrate ester plasticized polyol binder system. In this article, plasticized polyurethane networks of polycaprolactone (PCP) and hydroxyl-terminated polybutadiene (HTPB) with different crosslinker content [0 to 0.20 parts] at various stoichiometric NCOOH ratios (r-value) [0.8 to 1.0] were studied. Five numbers of polyurethane networks of 1,2,4-butanediol trinitrate (BTTN) plasticised PCP were formulated at each r value 0.8, 0.9 and 1.0 using 0, 0.05, 0.10, 0.15 and 0.20 parts of trimethylolpropane (TMP) crosslinker. Similarly, five numbers of dioctyl adipate (DOA) plasticized HTPB based polyurethane networks were formulated at r-value of 0.8. FT-IR spectra of these polyurethane networks (PUNs) were recorded for functional group identification. Stress-strain behavior of PUNs was studied for understanding the effect of TMP content and r value on mech. properties. Hard segment content of PUNs were calculated and its influence on network characteristics and mech. properties was evaluated. CLD values (ν) increased with increase of hard segment content of PUN and the values quantified by different approaches followed the trend νe (by solvent swelling method) > νne2(by Initial modulus method)>νne1 (by Mooney Rivlin method).
