All begin with the formulation of cuprous sulfide as given by: 2Cu +S [Cu.sub.2]S This may be followed by one of three reactions: (1) Reacting with additional sulfur to form cupric sulfide: [Cu.sub.2]S+S 2CuS (2) Reacting with an active rubber sulfur species: [Cu.sub.2]S+R S* [Cu.sub.2] S S R (3) Reacting directly with the rubber, in this case adding directly to the double bond: [Cu.sub.2]S+R CH=CH R R CH CH R S H Cu
Even when an ample amount of cuprous sulfide is available, there needs to be a sufficient number of sites of unsaturation present to gain adhesion between the wire and rubber.
