Figure 2 The distance dependence characterizing exclusion of small solutes from macromolecular surfaces follows the same exponential behavior as the hydration force between macromolecules. The extent of exclusion can be extracted from the dependence of forces on solute concentration. ITexcess is the effective osmotic pressure applied by the solute in the bulk solution on the macromolecular phase, and np is the maximal pressure from complete exclusion, riexcess/rio = 1 then corresponds to complete exclusion and n excess/Ho = 0 means no inclusion or exclusion. The distance dependent exclusion the polar polyols adonitol (A) and glycerol ( ) from hydrophobically modified hydroxypropyl cellulose (FIPC) and of the nonpolar alcohols i-propanol ( ) and methyl pentanediol (MPD) ( ) from spermidine +-DNA is shown. As in Fig. 1, interaxial spacings are converted to surface separations. The apparent exponential decay length varies between 3.5 and 4 A (solid lines indicate fits to the data).

The extension of these principles to molecules and macromolecules based on renewable resources has been applied to polymer chemistry and technology, mostly in two areas requiring viscous materials, namely (i) the preparation of liquid polyols to be used in the manufacture of polyurethanes, and (ii) the synthesis of macromol-ecular rheology modifiers. A typical polyol for the synthesis of polyurethane foams is obtained industrially from the oxypropylation of sorbitol, [3] whereas hydroxypropyl cellulose represents a major commodity for the rheological control of paints, foodstuff, cosmetics, etc. [4]. [Pg.274]

A systematic study has been reported concerning the influence of the specific water structure and diphylic nature of some cellulose ethers (methyl-, methyl-hydroxypropyl-, hydroxypropyl-, hydroxyethyl-, and hydroxyethylhydroxy-propyl-) on the properties of the aqueous solutions of these polysaccharide derivatives. The presence of non-polar groups in the cellulose ether macromolecule and of associated specific water structures account for the solution properties given by hydrophobic hydration and hydrophilic bonds. [Pg.132]
