Abstract

Blends of NR with EPDM and with a chemically modified EPDM have been investigated using a continuous-wave H NMR spectroscopy technique to determine the crosslink density within the NR phase of the blends. In all cases the observed crosslink density was higher than in a NR control vulcanisate containing the same level of curatives. The modified EPDM gave blends of superior physical properties but the modification had little effect on the course of sulphur vulcanisation within the blends.
