DeLink system

Combinations of thiophilic chemicals currently used by the rubber industry that fall within, or are close to, the scope of the patents covering the DeLink system. 

At the conclusion of the work, the project was regarded as having achieved its primary target of formulating new systems to improve the scorch performance that could be obtained by a commercial DeLink system by using combinations of chemicals that were less active at the revulcanisation stage. However, the workers found that no single system could be used for all applications as each had its limitations. There were two principal conclusions ... 

If Aw < Aw, tte system can still attain tte maximum possible valtK Xj = 1/2 at or below without losing its stability. If, in contrast. Aw > Aw, , the equilibrium condition delink by Eq. (26) becomes multi-valued. At T, the qfstem reactes only a concentration < 1/2, at whidi according to Eq. (2.27) it be< mes instable. When is exceeded the number of defect chain-molecules corresponding to equilibrium can only be produced by an abrupt jump to form extensive (D D)-clusters with a reduced number of (D 0)-pairs at their boundaries. The maximum possible value = 1/2 remains in this case purely fictitious.
