摘要： PURPOSE:To improve the mechanical strength, etc., of an alpha-olefin dimerization catalyst by depositing specified amts. of Na and K on a compression-molded granular carrier having a specified content of carbon, consisting of the anhydrous potassium carbonate having a specified grain diameter and having a specified pore volume ratio and compressive strength. CONSTITUTION:Carbon is added by 0.6-3wt.% (based on anhydrous potassium carbonate) to the anhydrous potassium carbonate having 150-600mum average grain diameter, contg. 1-15wt.% powder having 600mum grain diameter and having 0.50-0.70g/ml bulk density, and sufficiently mixed. The powder is compression-molded by a compression-molding machine to obtain a compression-molded carrier having 22-38% pore volume ratio and 1.5-15kg/cm G compressive strength. An alkali metal consisting of 20-90g atom% Na and 80-10g atom% K is deposited on the carrier to obtain the alpha-olefin dimerization catalyst.

摘要： PURPOSE:To improve extensibility without spoiling the transparency, heat- resistant property, resistance to chemicals, separatability and the like of poly(4- methylpentene-1), by a method wherein the molding of poly(4-methylpentene-1), containing the specified amount of unsaturated carbonic acid or the derivative thereof as the amount of graft, is oriented under a temperature up to the melting point thereof. CONSTITUTION:The molding of poly(4-methylpentene-1), containing 2X 10 -1X10 wt% of unsaturated carbonic acid or the derivative thereof as the amount of graft, is oriented under a temperature up to the melting point of the molding. The extensibility of the poly(4-methylpentene-1) under a tempera ture up to the melting point of the same is improved by grafting the poly(4- methylpentene-1) with the small amount of unsaturated carbonic acid or the derivative thereof whereby an oriented molding, excellent in transparency, rigidity, electric properties or shrinkability, may be obtained. When the containing amount of unsaturated carbonic acid or the derivative thereof is up to 2X10 , the extensibility of the molding is not improved, however, when the containing amount of the same exceeds 1X10 wt%, the molding becomes cloudy and the appearance of the same may be spoiled.

摘要： PURPOSE:To obtain continuously a high-quality low-molecular weight polymer with a simple apparatus by feeding a polymer to an extruder, melting it, transferring the molten polymer at a constant rate to a tubular thermal decomposer through a constant rate transfer means connected to the extruder, and thermally decomposing the polymer. CONSTITUTION:A starting polymer (e.g. polyethylene) is fed through a hopper 5 to an extruder 1, where the polymer is molten, kneaded and extruded from the exit 12. The extruded molten polymer is transferred at a constant rate to a tubular thermal decomposer 2 through a constant rate transfer means 4 (e.g. gear pump) connected to the extruder 1. The molten polymer is heated by a heater 3 provided in the decomposer 2 and thermally decomposed to form a low-mol.wt. polymer, which is withdrawn from the exit 22. The obtained low-mol. polymer can be desirably used as a wax for use in a pigment dispersant, a rubber processing aid, a coating additive or the like.
