    摘要： Halogen-containing polymer backbone chains containing grafts of polyethers derived from halogen-substituted oxiranes or oxetanes are described. The graft polymers are produced by contacting polymers containing reactive halogen with halogen-substituted oxiranes or oxetanes in the presence of a catalytic amount of an organoaluminum compound which has been modified with water, boron trifluoride and/or phosphorus pentafluoride. The graft polymers are useful as such for films, fibers, coatings, etc., and are particularly useful for blending with other materials to provide special properties such as flame resistance, impact resistance, etc.

    摘要： OXIRANES ARE POLYMERIZED USING AS THE CATALYST THE PRODUCT OBTAINED BY REACTING A DIHYDROCARBON ZINC COMPOUND, SUCH AS DIETHYLZINC, WITH WATER IN A MOLAR RATIO OF WATER TO ZINC COMPOUND OF FROM ABOUT 0.2:1 TO ABOUT 1.2:1. HIGHER MOLECULAR WEIGHT POLYMERS AND/OR HIGHER YIELDS OF POLYMER ARE OBTAINED THAN WHEN THE DIHYROCARBON ZINC COMPOUND IS USED WITHOUT PREREACTING IT WITH WATER.

    POLYETHERS ARE PROVIDED THAT HAVE PHOSPHINYL GROUPS ATTACHED TO ALIPHATIC CARBONS IN SIDE CHAINS PENDANT FROM THE POLYETHER BACKBONE. THESE PHOSPHINYL CONTAINING POLYETHERS ARE OBTAINED BY REACTING A POLYETHER CONTAINING A HALOALKYL GROUP, AS FOR EXAMPLE, POLY (EPIBROMOHYDRIN), WITH AN ORGANIC PHOSPHITE, PHOSPHONITE OR PHOSPHINITE. SAID PHOSPHINYL GROUP HAS THE GENERAL FORMULA
