METHOD FOR PREVENTING FOULING IN SLURRY SYNTHETIC PROCESS

摘要

PURPOSE: A method for preventing fouling in a slurry synthetic process is provided which is able to efficiently prevent the fouling by throwing a specific fouling preventing agent in the process of the slurry synthetic process producing olefin monomer. CONSTITUTION: In preparing a single polymer or a copolymer of an olefin monomer in a reactor by a slurry synthetic process using a metallocene supported catalyst, a fouling preventing agent of the following formula 1 of R¬1-N{(R¬2O)nH}2, where R¬1 is either alkyl or alkenyl radical having 4-25 carbon atoms; R¬2 is diradical having 1-4 carbon atoms; and n is an integer of 1-5, is added in an amount of 0.1-3,000 parts per million to a weight of a polymerizing medium to prevent the fouling of an inside wall of the reactor.
