Abstract
Dispersions of low pressure polyolefines obtained by using complex metal catalysts consisting of reducible compounds of metals of Groups IVb to VIb and VIII of the Mendeleef Periodic Table and hydrides or organic compounds of metals of groups Ia to IIIa of the Periodic Table, are purified by exposing the dispersion in the presence of the decomposing or washing liquid to an ultrasonic field, and then purifying in a conventional manner. In the preferred process the dispersion is mixed between 20 DEG and 80 DEG C. with 0.1 to 10% of methanol or water, then conducted through an ultrasonic field in the frequency range 20 kc./s. to 1.5 Mc/s., the contact time being 0.5 seconds, then the methanol or water is separated and 1 to 20% of water is then added to the polyolefine phase which is then submitted at a temperature between 20 DEG and 70 DEG C. to a second ultrasonic treatment, frequency range 8 kc./s. to 1.5 Mc/s. and contact time 0.5 seconds, and finally the washing water is removed and the polyolefine obtained.
