In a previous work, two methods using rheometric parameters to calculate the kinetic constant were compared, and the results showed that the higher significative variables could be accurately determinated in opposition to the lower significative ones. Thus, a modification is suggested in this article, by limiting the conversion of the cure reaction to 80% to minimize the effects due to the deceleration curing. This allowed a precise determination of which variables have an effective influence on the cure kinetic constant. © 2003 Wiley Periodicals, Inc. J Appl Polym Sci 91: 506–509, 2004
