Abstract
PURPOSE: To obtain propylene copolymer having excellent heat-seal, antifreezing, transparence, sliding, and blocking properties, by polymerizing proplyene, ethylene and butene-1 in a specified solvent in the presence of titanium trichloride and org. aluminum cpd.
CONSTITUTION: Propylene, ethylene and butene-1 are copolymerized in a liquid medium having a solubility parameter of 7.0 (cal/cc)1/2 or below in the presence of a catalyst consisting of (a) titanium trichloride, obtd. by reducing titanium tetrachloride with org. aluminum cpd, and activating the reduced product, and (b) org. aluminum cpd. in a molar ratio of (b)/(a) of 20W100, preferably 30W70. The polymer slurry drawn out is introduced into the upper part of a countercurrent scrubbing tower, and contacted with liquid phase medium having a solubility parameter of 7.0 (cal/cc)1/2 or below supplied from the bottom of the tower in order to wash the polymer.
