Attempts were made to prepare dinitropropyl vinyl ether DNPVE prepolymers of a molecular weight range of 2,000 to 4,000 with hydroxy functionality for use in cast-curable energetic binder systems. Two approaches were pursued. First, part of the dinitropropyl side chains in Poly-DNPVE were reduced to monoitropropyl groups and then hydroxymethylated with aqueous formaldehyde. The desired hydroxy-functional polymer was formed in excellent yield. In a second approach, DNPVE monomer was polymerized using initiator systems capable of introducing functional groups. The system, epichlorohydrin SnC14DNPVE, gave an incompletely characterized product of the expected elemental composition. However, the structure of the product was not determined.
