Total Claims: 10
Claim 1
Independent Claim
141 words
IN A PROCESS FOR POLYMERIZING OR COPOLYMERIZING VICINAL ALKYLENE OXIDES IN THE PRESENCE OF A CATALYST TO FORM THE CORRESPONDING HOMO- OR COPOLYMERS, THE IMPROVEMENT WHEREIN THE POLYMERIZATION OR COPOLYMERIZATION REACTION IS PERFORMED IN THE PRESENCE OF A CATALYST COMPRISING THE REACTION PRODUCT PERFORMED AT A TEMPERATURE OF 100*-300*C. BY REACTING OUTSIDE OF THE POLYMERIZATION SYSTEM: I. AT LEAST ONE METAL HALIDE SELECTED FROM THE GROUP CONSISTING OF A COMPOUND OF THE FORMULA ALX3, WHEREIN X MEANS CHLORINE OR BROMINE, A COMPOUND OF THE FORMULA MX4, WHEREIN X IS AS DEFINED ABOVE, AND M IS A METAL SELECTED FROM THE GROUP CONSISTING OF TI, ZR, HF, SI, GE, AND SN AND A COMPOUND OF THE FORMULA SNX2, WHEREIN X IS AS DEFINED ABOVE, WITH AT LEAST ONE REACTANT (II) SELECTED FROM THE PHOSPHORUS-CONTAINING COMPOUNDS OF THE FOLLOWING 11 GROUPS: II. (1)
