    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: A process for determining the quality of polymerization catalysts includes: (a) catalyst preparation; (b) polymerization of a monomer with the catalysts; (c) isolation of the polymers obtained under (b); and (d) characterization of the polymers. The process is carried out automatically in an arrangement of n vessels, steps (a) to (d) are all parallel steps, all sequential steps, or some in parallel and the rest in sequence and n at least 2. An Independent claim is included for an automated device for determining catalyst quality comprising: (A) a synthesis module and (B) an analysis module for determination of soluble and insoluble polymer fractions, where A and/or B contain at least 4 vessels and cumulative volume of the A and B vessels does not exceed 100000 ml.
