The multifunctional effect of the dihydrogen phosphate of ε‐aminocaproic acid (DHPh ε‐ACA) on isoprene rubber compounds is presented in this paper. DHPh ε‐ACA is the product of interaction of polymeric, oligomeric or monomeric ε‐aminocaprolactam and phosphoric acid, with an excess of the acid. This interaction offers an additional possibility for the utilisation of waste or non‐standard amide‐group‐containing materials by converting them into a phosphorus‐containing substance. DHPh ε‐ACA acts as dispersant and plasticiser during the mixing and, later, during the vulcanisation participates in the formation of a very flexible vulcanisation network, making the vulcanisates very stable to dynamic loads—the number of cycles at break increases by up to one order of magnitude. DHPh ε‐ACA acts also as an antistatic agent and the addition of 2–5 phr to non‐polar isoprene rubber turns it into an antistatic material. Copyright © 2004 Society of Chemical Industry
