Abstract
A method of determining the quality of polymerization catalysts comprises a) provision of the catalysts, b) polymerization of a monomer using these catalysts, c) isolation of the polymers obtained in b), d) characterization of the polymers, wherein the method is carried out in an assembly of n vessels in an essentially automated fashion, where the steps a) to d) are all carried out in parallel or are all carried out sequentially or some of the steps a) to d) are carried out in parallel and the remainder are carried out sequentially and n is a natural number greater than or equal to 2.

A method of determining the quality of polymerization catalysts, which comprises
- a) provision of the catalysts,
- b) polymerization of a monomer using these catalysts,
- c) isolation of the polymers obtained in b),
- d) characterization of the polymers,
- wherein the method is carried out in an assembly of n vessels in an essentially automated fashion, where the steps a) to d) are all carried out in parallel or are all carried out sequentially or some of the steps a) to d) are carried out in parallel and the remainder are carried out sequentially and n is a natural number greater than or equal to 2.
An apparatus for the essentially automated determination of the quality of polymerization catalysts, consisting essentially of A) a synthesis module and B) an analytical module for determining soluble and insoluble polymer fractions, where A) and/or B) each comprise at least four vessels and the respective cumulated volume of the vessels of A) or B) is in each case not greater than 100000 ml.
An apparatus for the essentially automated determination of soluble and insoluble polymer fractions, wherein this apparatus comprises an assembly of at least four vessels, metering devices, stirring and/or shaking devices, heating and/or cooling facilities for each of these vessels and a control unit for these functions and the cumulated volume of these vessels is not greater than 100000 ml.
