Process for producing high molecular weight polymers of alkylene oxides
Abstract
Abstract A PROCESS FOR PRODUCING A HIGH MOLECULAR WEIGHT POLYMER OF AN ALKYLENE OXIDE WHICH COMPRISES CONTACTING AN ALKYLENE OXIDE WITH A NOVEL CATALYST AT A TEMPERATURE OF FROM -50*C. TO +150*C., SAID CATALYST BEING PREPARED BY PARTIALLY HYDROLYZING AN ALUMINUM ALKOXIDE WITH WATER IN AN AMOUNT OF 0.01 TO 2.8 MOLES PER MOLE OF THE ALKOXIDE IN A LIQUID, INERT MEDIUM AND MIXING THE RESULTING PARTIAL HYDROLYZATE WITH AN ORGANO-METALLIC COMPOUND OF A METAL OF GROUP II OR III OF THE PERIODIC TABLE IN AN AMOUNT OF 0.001 TO 2.5 MOLES PER MOLE OF THE STARTING ALUMINUM ALKOXIDE. WHEN THE ABOVE POLYMERIZATION IS EFFECTED IN THE PRESENCE OF A TERTIARY AMINE, THE POLYMERIZATION DEGREE IS INCREASED.
