Not for specificationpurposesAll measurements at25 C, 1 atm unless notedThis material is a difunctional aziridine amide derived from isophthalic acid andpropylene HX-752 belongs to the chemical class of acyl aziridines which react withcarboxylic acids to form ring-opened ester-amide linkages and with alcohols in thepresence of acidic catalysts to form ring-opened ether-esters. These reactions take placeat relatively low temperatures and without the evolution of byproducts, so HX-752 canbe used as a chain extender or crosslinker to cure carboxyl-functional polymers or toharden hydroxyl-functional polymers in the presence of acidic species. HX-752 has found use in solid rocket propellant formulations where it acts as abonding agent for ammonium perchlorate in polybutadiene matrices.
