Abstract
An improvement in a method for evaluating the efficiency of polymerization inhibitors is disclosed, wherein the improvement comprises: PA1 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, PA1 B) collecting the polymer-containing solution, PA1 C) measuring the degree of polymerization of the monomer in the collected solution, and PA1 D) re-subjecting the polymer-containing solution to the test conditions of A).
