“…The values of x and M" used to calculate Mc in Figure 1 are consistent with those reported by Fort and Polyzoidis. 64 We and clearly reveals that Mc is far more sensitive to than Mn, particularly for the lightly cross-linked gels at the highest value of used in these calculations ( = 0.461). In view of these results, we used Ma = 75000_and the average value of = 0.375 in our final calculations in X-ray Photoelectron Spectroscopy.…”

A series of poly(2-hydroxyethyl methacrylate) gels cross-linked with different concentrations of ethylene glycol dimethacrylate were examined by static secondary ion mass spectrometry (SIMS). Changes in the peak intensities of atomic versus molecular secondary ions were observed in negative ion SIMS as a function of cross-linker concentration. These changes in the distribution of secondary ions as a function of cross-linker concentration, and thus as a function of molecular weight between cross-links, are discussed with respect to the factors affecting secondary ion emission during the SIMS process. The sensitivity of static SIMS to the concentration of cross-links in the polymer chains on the surface of the polymer, demonstrated by this study, may advance the study of technologically relevant surface modifications involving surface cross-linking.

“…We assumed these values of polymer molecular weights in the calculation of since values of a corresponding to these polymer molecular weights were available from Fort and Polyzoidis. 64 The value of x in their calculations ranged from 0.37 to 0.461. We examined the variation in Mc as a function of varying x and M" (Figure 1).…”

The viscosimetric behaviour and the preferential solvation of poly(methacry1ic acid), (PMA, poly(1-carboxy-1-methylethylene)) and poly(2-hydroxyethyl methacrylate), (PHEMA, poly[l-(2-hydroxyethoxycarbonyl)-1 -methylethylenel) in water/2-~hloroethanol mixtures were studied. The system PHEMA/water/2chloroethanol is a typical polymer/solvent/precipitant system in which 2-chloroethanol is preferentially solvated in the whole range of solubility. On the contrary, the system PMA/water/2-chloroethanol is a typical cosolvent system which exhibits the so-called inverse adsorption. This difference is attributed to the more hydrophilic character of the carbonyl group in PMA.
