“…For simplicity, VCG (4 -6) also discounted the equilibrium spreading pressure, especially in their Lewis acid-base methodology. However, there is new evidence (27)(28)(29)(30)(31) showing otherwise. For some polymer surfaces, Jacob and Berg (32) found e 's amounting to approximately 8 -27% of the total initial work of adhesion.…”

“…The validity of their results may be in question, because of their use of mercury as the reference. In comparison with the data generated by other workers (28,29,31), their results do appear somewhat high, so we used the lower limit of their e 's for our calculations.

We present our unified Lewis acid-base approach to adhesion and solvation at the liquid-polymer interface. This approach is to complement the original methodologies proposed by Fowkes and by van Oss, Chaudhury and Good (VCG). Intermolecular interactions are primarily dominated by dispersion, d, hydrogen bonding, h, and secondarily affected by orientation, 0, and induction, i. Generally, the polarization component, p, represents both i and o interactions. Fowkes suggested that the acid-base component, yab, of the surface tension should consist of both h and p interactions. However, VCG proposed that the acid-base components, yab, result solely from hydrogen bonding, yh, that is equivalent to 2(y+ y J ' I 2 , where y ' and y ~ are the two hydrogen bonding parameters. VCG defined yL as the Lifshitz-van der Waals component consisting of d, o and i contributions, thus, surface tension, y, equals yab(VCG)+yLW. Both Fowkes and VCG assumed that the polar interactions for a liquid on a low energy surface are negligible. Now, we assume otherwise, and we treat the specific acid-base interaction to be hydrogen bonding. In addition, we also take into account the nonspecific polarization, p, interaction in terms of the equilibrium spreading pressure, re, resulting from the adsorption of a liquid vapor on the polymer surface. Thus, our unified approach uses the dispersion component, yd, of Fowkes, the hydrogen bonding, h, of VCG and the polarization, p. in terms of re. The difference between the initial (theoretical) and equilibrium (experimental) surface tensions is re, and others have observed that n, on some polymers is substantial. The determination of several initial surface tensions of polymers by considering the effect of polarization is discussed.In the Appendix, we shall illustrate that this polar component, re, is equivalent to the LESR polarity-dipolarity parameter, II*, (represented by the same symbol but in different context) for the solvatochromic treatment. Furthermore, the surface tension components, y d , y ', y -and x,, are now somewhat comparable with the four parameters in the original Taft-Kamlet relationship, 6, a, 9, and n'. Thus, our proposed *Honordry Professor, Chinese Academy of Sciences. Tel./Fax: 716-872-291 5, e-mail: Ihlee@frontiernet.net 163 Downloaded by [New York University] at 09:32 01 August 2015 164 L.-H.

It is often pointed out that low water absorption and moisture permeability are drawbacks of polypropylene (PP). In this study, blending with an amorphous polymer was used to modify PP. For improving the properties of PP without any property depression, PP was blended with phenolic resin-Novolak type (PRN). PP/PRN blends were investigated by a contact angle test for surface properties to determine whether PP had hygroscopic characteristics due to the existence of PRN in the blends. In addition, for the sake of efficient investigation in this blend, chemical structure, mechanical measurement, thermal analysis, and morphological observations were also studied.
