A method for determining the polymerization activity of metallocene catalysts with the uv / vs - spectroscopy

摘要

A method for determining the activity of metallocene catalysts in the polymerization of alk - 1 - one or vinylaromatic compounds with uv / vis - spectroscopy by means of dollars a a) determining the characteristic uv / vis - extinction values of certain metallocene catalyst - samples, dollars a b) determination of the polymerization activities, this metallocene catalyst samples, dollars a is c) creating a calibration curve from the respective values - pairs of a) and b), dollar a d) determining the polymerization activities of a desired metallocene catalyst, by measuring the uv / vis - extinction and able transmitter associated polymerization activity from the calibration curve c), dollar a characterized in that it is in a) to d) in order to metallocene catalysts are immobilized on carriers.
