PROBLEM TO BE SOLVED: To provide a method for preparing polymers by means of ring-opening metathetic polymerization, in which a catalyst is to be generated from inexpensive ruthenium compounds, but does not require the above-described activating agents.SOLUTION: The present invention relates to a method for preparing polymers by means of ring-opening metathetic polymerization, comprising the following steps of: a) providing a reaction mixture consisting of a cycloalkene or a cycloalkene mixture, b) adding a ruthenium compound of the general formula RuXXLL(I); c) adding a chain transfer agent in a molar ratio in the range from 1:5 to 1:1,000 based on the cycloalkene or the sum total of the cycloalkenes in the cycloalkene mixture; and d) converting at a temperature within a range from 0°C to 250°C. |
