AGENT FOR NUCLEATION OF POLYOLEFIN AND ELIMINATION OF FOULING IN A GAS PHASE POLYMERISATION REACTOR

摘要

An agent for elimination of formation of polyolefin powder fouling on walls of gas-phase polymerization reactors and their recycles and for preparation of a nucleated polyolefin directly during polymerization of 1-olefins on Ziegler-Natta catalysts. This agent remains dispersed in the polyolefin material and it acts as a nucleator. It comprises at least one compound prepared by the reaction of an organoaluminium with a compound based on derivatives of amides of aliphatic or aromatic carboxylic acids
