Polyurethanes from fluoroalkyl propyleneglycol polyethers

A description is given of highly stable polyurethane polymers prepared by reacting a polyether with a diisocyanate. Compounded stocks of these polymers may be shaped and cured in conventional equipment used in the rubber industry. The solutions are dispersed gels prepared from the polymers and may be used for forming supported or unsupported films for coating fabrics or solid surfaces, and for forming adhesive bonds between a wide variety of plastics, elastomers, fabrics, metals, wood, leather, ceramics and the like

Fluorohydroxy ethers

The preparation of poly(polyfluoroalkylene-glycol) mono (hydroxy polyfluoroalkylene) ethers from fluoroalkylene oxides is described

Fluorine containing polyurethane

A polyurethane polymer prepared by reacting a hydroxy-terminated polyformal with an organic diisocyanate is presented

Synthesis of various highly halogenated monomers and polymers

Halogenated polyurethane and polycarbonate are synthesized and found to be LOX compatible but dependent upon the type nitrogen bonding
