Process for polymerizing cyclic oxides with a catalyst consisting of an organozinc compound and another material

Abstract

Abstract A PROCESS IS DISCLOSED FOR MAKING POLYETHERS WHICH COMPRISES MIXING UNDER ANHYDROUS NON-OXIDIZING CONDITIONS (A) AT LEAST ONE COMPOUND OF THE FORMULA ZNR2 IN WHICH EACH R IS A MONOVALENT HYDROCARBON RADICAL, AT LEAST ONE R BEING NON-AROMATIC, FROM ABOUT 0.05 TO ABOUT 1.5 MOLS PER MOL OF (A) OF (B) OF AT LEAST ONE COMPOUND SELECTED FROM THE GROUP CONSISTING OF PROMARY AROMATIC AMINES, AMIDES, CYCLOALKADIENES OF FROM 5 TO 6 CARBON ATOMS AND SECONDARY AMINES COMPOSED OF AT LEAST ONE NITROGEN ATOM, FROM ABOUT 2 TO ABOUT 14 CARBON ATOMS PER NITROGEN ATOM AND AT LEAST 6 TOTAL HYDROGEN ATOMS PER NITROGEN ATOM,ANY REMAINING STOMS IN THE SECONDARY AMINES BEING SELECTED FROM THE GROUP CONSISTING OF ETHEREAL OXYGEN ATOMS, HYDROXYL OXYGEN ATOMS AND THIOTHEREAL SULFUR ATOMS, ANY NITROGEN ATOM HAVING TWO AROMATIC RINGS ATTACHED THERETO BEING PART OF A CYCLIC AMINO COMPOUND, AND FROM AOBUT 10 TO ABOUT 10,000 MOLS PER MOL OF (A) AND (B) OF (C) AT LEAST ONE POLYMERIZABLE ORGANIC CYCLIC OXIDE MONOMER INCLUDING IN ITS STRUCTURE AT LEAST ONE OXYGEN-CARBON RING CONTAINING ONE OXYGEN ATOM AND FROM 2 TO 3 CARBON ATOMS AND UP TO 70 CARBON ATOMS, AND THEN, AT A TEMEPERATURE SUFFICIENT OF EFFECT POLYMERIZATION, POLYMERIZING SAID CYCLIC OXIDE MONOMER THROUGH SAID OXYGEN-CARBON RING WHEREBY SAID RING OPENS TO FORM SUBSTANTIALLY LINEAR POLYETHER STRUCTURES. THESE POLYMERS ARE USEFUL AS PLASTICIZERS, IN MAKING COATED FABRICS, PACKING FILMS, ELASTIC FIBERS, AND ADHESIVES AS WELL AS IN MAKING TIRES, SHOE HEELS, RAINCOATS, UPHOLSTERY MATERIAL, FLOOR MATS AND MOLDED ARTICLES.
