Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
In an epoxy system modified with a carboxyl-terminated butadiene acrylonitrile copolymer (CTBN) rubber, the cure kinetics was studied in terms of the Kissinger equation (eqn. 1) and of the autocatalytic cure rate expression (eqn. 2). By the former equation, a simple n-th order rate equation, DSC measurements allowed to determine the activation energy and the pre-exponential factor; by the latter equation, isothermal DSC analysis allowed to determine the rate constants and reaction orders. The two methods were found suitable to follow the cure kinetics of the epoxy system. In the system modified with CTBN, the cure rate was initially higher than that in the system with CTBN added, on account of the catalytic role of the -COOH groups in CTBN. At a degree of conversion equal to about 0.6, the cure rate was inverted on account of the formation of the CTBN domain.
