Abstract: PURPOSE:To produce an acetylenic high polymer continuously at low manufacturing cost, by employing a loop polymerizer. CONSTITUTION:From a material feeder (numeral 1 is a feeder for acetylene, 2 is a feeder for a solvent, 3 is a feeder for a base catalyst, 4 is a feeder for a promotor, and 5 is a feeder for a comonomer), each material is fed continuously to a loop polymerizer 6, polymerized while being moved through the inside of the loop at a high speed by means of a screw 7, and the polymer is withdrawn after a predetermined residence time by opening a discharge valve 8. An equal or smaller amount of a diethylene monomer may be used in combination with acetylene (derivative). A Ziegler catalyst, a Luttinger catalyst or the like is used. The polymerization temperature is preferably about -100-200 deg.C, and the polymerization pressure is preferably about 10kg/cm or below.
