Abstract
An improvement in a method for evaluating the efficiency of polymerization inhibitors is disclosed, wherein the improvement comprises: A) producing dissolved polymer in a solution comprising monomer and at least one inhibitor by means of any test known in the art to be useful for evaluating polymerization inhibitors, B) collecting the polymer-containing solution, C) measuring the degree of polymerization of the monomer in the collected solution, and D) re-subjecting the polymer-containing solution to the test conditions of A).
Claims6
A test method for evaluating the effectiveness of polymerization inhibitors in their ability to prevent polymer growth via a living polymerization mechanism when the living polymer is dissolved in its monomer comprising:
- A) producing dissolved polymer in a solution comprising monomer and at least one inhibitor by means of any test known in the art to be useful for evaluating polymerization inhibitors,
- B) collecting a first polymer-containing solution,
- C) measuring the degree of polymerization of the monomer in the first polymer-containing solution,
- D) re-subjecting the first polymer-containing solution to the test conditions of A) to produce a second polymer-containing solution,
- E) collecting the second polymer-containing solution,
- F) measuring the degree of polymerization of the monomer in the second polymer-containing solution, and
- G) comparing the measurements obtained in steps C) and F), whereby an indication of the ability of the polymerization inhibitor to prevent or allow polymer growth is obtained.
