Triazole cross-linked energetic polymer networks obtained from the reaction of dialkyne curing agents with glycidyl azide polymers (GAP) or poly(2,2-[bisazidomethyl]propane-1,3-diyl carbonate) (poly[BAMPC]) were studied, and their thermal and mech. properties are reported. The dialkynes studied include bis(propargyl)ether (BPE), bis(propargyl)malonate (BPM), and 4,4â?diacyanohepta-1,6-diyne (DCHD), three compounds previously described as curing agents for glycidyl azide pre-polymers. The cured polymer networks display a wide range of properties dependent on the nature of the azido pre-polymer, the nature of the dialkyne, the alkyne/azide molar ratio, and the mol. weight of the pre-polymer used. Results confirm that the three dialkynes are effective curing agents able to form rigid networks out of either pre-polymer and that the lighter mol. weight BPE and DCHD both improve mech. properties of cured networks with less dilution of the systemâ²s energetic content. Triazole cross-linked poly(BAMPC) networks were studied for the first time, and promising phys. and mech. properties are reported. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Related Products of 102-09-0).
Diphenyl carbonate (cas: 102-09-0) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.
