General Applicability to Poly Sty-co-DVB

The results obtained for this correlation [130] are recorded in Fig. 12, which shows that at each given temperature of polymerization reported by Staudinger, x is a linear function of y as expressed by  

A more critical test of the gravimetric method for determination of crosslink density (1/7.) would be a comparison of results obtained on the basis of Eq. 16 for poly(Sty-co-DVB) samples made via free-radical polymerization in various 

Claimed is the DVB mole fraction (y) in the monomer reaction mixture made to undergo polymerization by the manufacturer. 

Observed is the average value for the DVB mole fraction (x) in the polymer as determined by swelling measurements (Eq. 16) in 10 different liquids (including CHC13). 

The commercial sources of these samples, the mole fraction (y) of DVB in the monomer mixture made to undergo polymerization [138], and the corresponding average crosslink density (1/k, equal to approx, x when x is 0.1), determined on the basis of swelling in ten different liquids, are collected in Table 1, along with the corresponding linewidth (vi 2) observed in the 13C NMR spectra (Fig. 14).
