The tensile stress‐relaxation characteristics at room temperature of gum NR vulcanizates containing 10–20 phr of phosphorylated cashew nut shell liquid (PCNSL) prepolymer were studied at various strain rates and strain levels, in comparison with that containing the same dosage of 2‐ethyl hexyl diphenyl phosphate and the unmodified sample. Modification of NR with 10–15 phr of PCNSL resulted in improvements in tensile properties along with a lower degree of stress relaxation at the higher strain rates and strain levels. © 1997 John Wiley & Sons, Inc.
