Cross effective degree

Fig. 100.—Network activity, r/RT ol — 1 o ) — veIVy of GR-S cross-linked with persulfate plotted against the effective degree of cross-linking. The values of yn indicated represent primary degrees of polymerization. (Results of Bardwell and Winkler. )...

The first project [9] dealt with the evaluation of the effect of cross-linking degree (c.l.d.) in a series of five gel-type resins, on the diameter of Pd° nanoclusters obtained upon reducing resin-bound Pd centres. In this project c.l.d. was let to range from 1 to 9% mol (Figure 3). 

Gel-type cross-linked functional polymers, with moderate cross-linking degree (4-8% mol) are effective templates... 

The reactivity of a triphase reaction is influenced by the structure of the active sites, particle size, degree of cross-linkage, degree of ring substitution, swollen volume, and spacer chain of a catalyst pellet. All these make the triphase reaction a complicated one. Past efforts have carried out this investigation macroscopically. However, the mechanism and effects of the internal molecular structure of the polymer support have seldom been discussed. 

An estimate of the effective degree of cross-linking of the vulcanlzate can be calculated from the measured physical properties and the appropriate empirical equations. Even though these techniques have been developed to a high degree of sophistication, they do not provide an absolute means of characterizing the network structure of a vulcanlzate.
