Abstract
A method for evaluating the polymer growth inhibition ability of a compound or compounds is disclosed wherein the method comprises: PA1 A) weighing a dry seed of insoluble polymer capable of growing via a living polymerization mechanism; PA1 B) subjecting the seed of insoluble polymer to conditions capable of causing a living polymer to grow via a living polymerization mechanism; PA1 C) drying the seed; and PA1 D) weighing the seed a second time to determine any increase in weight; wherein the polymer growth inhibition ability of the compound or compounds is inversely proportional to any increase found in weight of the seed.
