Kinetics intercalation

The effect of the position of side chains on the intercalation kinetics of anthra-quinones,101 which are related to the aromatic moiety of daunomycin (13), was studied with the stopped flow SDS sequestration technique. Guest molecules 14—17 can have two different intercalation modes, a classic mode where both side chains are located in the same groove of the DNA helix (14 and 16) or a threading mode where the side chains are located in opposite grooves of the DNA (15 and 17) (Scheme 7). The relative position of intercalated 14 with respect to the DNA bases was suggested to be the same as for 13.

Vaia et al. [12] have observed that the kinetics of intercalation even under quiescent conditions (absence of external shear) are quite rapid. Using in-situ XRD (which monitors the angular shift and integrated intensity of the silicate reflections, Fig. 9) they studied the intercalation kinetics of model polymers (mono-disperse polystyrene) in organically modified fluorohectorite. 

The NPD data for the 300 degrees Kelvin run of the Stage 4 compound is seen in Figure 2. While the synthesis conditions used to make this sample were similar to the conditions used to make the Stage 2 compound, we believe that subtle differences in the nature of the starting graphite resulted in slower intercalation kinetics. In fact, this sample also contained a small amount of Stage 3 material. Both...

The existence of MAH groups along the EVA chains may disrupt the optimum combination of EVA with Cloisite SOB, or too strong polymer-organic silicate layer interactions may increase the frictional coefficient associated with polymer transport within the interlayer and result in slower melt intercalation kinetics. ...
