PROCESS FOR REMOVING INERT MEDIUMS FROM MACROPOROUS COPOLYMERS

摘要

the invention refers to a process of cut out of copolymers macroporosi inert environments in which in a first step, copolymer is subject to extraction with water vapor at the temperature of 100 to 125 degree c, water vapour movement up and down, and then wash with 2 - 3 volume of methanol for the removal compusilor nepolimerizabili, after which dries in the same plant, and in the second step,polystyrene copolymer which contains only is subjected to extraction with dichloromethane and after attainment of equilibrium concentration of solvent is replaced with another,the repeating 3 to 4 times with about 3 vol / vol pearls copolymer solvent solvent, removal is accomplished by filtration.drying is carried out with pearl inhibited solvent in the same plant, with steam.
