ABSTRACT:
Polyethers are formed by polymerizing oxetanes having one or two pendant groups which contain cyano moieties, particularly 3-cyanomethyl-3-methyl oxetane and 3,3-Bis(cyanomethyl) oxetane. The polyethers may also contain mer units derived from other cyclic ethers, including other oxetanes and tetrahydrofurans. The cyano group gives the polyether improved compatibility with nitrate ester plasticizers. The polyethers are curable with polyfunctional isocyanates to form binders for propellants, explosives or the like.
