    Abstract: PROBLEM TO BE SOLVED: To provide a method which can quickly and inexpensively evaluate the quality of a number of catalyst samples for catalyzing polymerization. SOLUTION: The method of determining the quality of polymerization catalysts comprises (a) a step of providing catalysts, (b) a step of carrying out the polymerization of a monomer using these catalysts, (c) a step of isolating polymers obtained in step (b), and (d) a step of characterizing the above polymers, and the above method is carried out in an assembly of n vessels in an essentially automated fashion, and the steps (a) to (d) are all carried out in parallel or are all carried out sequentially or some of the steps of (a) to (d) are carried out in parallel and the remainder are carried out sequentially, and n is a natural number of ≥2.

    Abstract: PROBLEM TO BE SOLVED: To provide a propylene polymer which has a high rigidity/strength ratio and low chlorine content, and can be produced by a process with high productivity. SOLUTION: A propylene polymer containing a matrix comprising a propylene homopolymer and a copolymer of propylene with other alkene is first dissolved in boiling xylene, the solution is cooled at a cooling rate of 10 deg.C per hr to 25 deg.C, the temperature is then raised to separate the propylene polymer into fractions of various solubilities according to the stereoregularities of polymer chains and the comonomer distributions, wherein the matrix remaining undissolved when the cooled propylene polymer solution is heated to 80 deg.C satisfies one or more of the following conditions: i) the matrix remains undissolved in an amount above 20 wt.% when further heated to 112 deg.C; ii) it remains undissolved in an amount above 8 wt.% when further heated to 117 deg.C; and iii) it remains undissolved in an amount above 1 wt.% when further heated to 122 deg.C.

    Abstract: A polymer mixture with good processing properties, e.g. for blown or cast film, contains an ethylene copolymer and another ethylene copolymer with a higher density and a broader molecular weight distribution. A polymer mixture is claimed containing at least 40-85 wt% ethylene copolymer (A) with a density of 0.91-0.93 g/cm , a high-load melt flow rate (HLMFR; 190/21.6) of 5-60 g/10 mins. and a mol. wt. distribution (Mw/Mn) of not more than 3, and more than 15 but not more than 60 wt% ethylene copolymer (B) with a density of 0.93-0.945 g/cm , an HLMFR of 8-20 g/10 mins. and an Mw/Mn ratio of at least 7. Independent claims are also included for (a) a process for the production of film from this polymer mixture; (b) film produced from the polymer mixture.
