This study reports the relationship between glass transition temperature (Tg) and tributoxyethylphosphate (TBEP) concentration in acrylonitrile-butadiene rubber (NBR) gum vulcanisates. A linear relationship with weight fraction of+ TBEP was observed for up to 37 weight percent TBEP and the change in Tg over this range was high. However, the Fox-Hoy relationship between 1/Tg provided a better fit to the data. This observation provides a particularly reliable basis for estimating + plasticiser levels through measurements of Tg. The Gordon-Taylor relationship did not provide a good basis for predicting the Tg of the plasticised rubber. A much lower dependence of Tg on crosslink density was also observed.
