CA 2381152

A method for evaluating the polymer growth inhibition ability of a compound or compounds is disclosed wherein the method comprises: A) weighing a dry seed of insoluble polymer capable of growing via a living polymerization mechanism; B) subjecting the seed of insoluble polymer to conditions capable of causing a living polymer to grow via a living polymerization mechanism; C) drying the seed; and 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.

L'invention concerne un procédé d'évaluation de la capacité d'inhibition de croissance de polymère d'un ou plusieurs composés. Ledit procédé consiste à : A) peser une semence sèche de polymère insoluble capable de croître grâce à un mécanisme de polymérisation vivante ; B) exposer la semence de polymère insoluble à des conditions capables d'induire la croissance du polymère vivant par un mécanisme de polymérisation vivante ; C) sécher ladite semence ; et D) peser la semence une deuxième fois, de manière que l'augmentation de poids soit déterminée. Par ailleurs, la capacité d'inhibition de croissance de polymère du ou des composés est inversement proportionnelle à toute augmentation de poids constatée de la semence.
