A new strictly alternating comblike amphiphilic polymer based on PEG. 2. Associative behavior of a high molecular weight sample and interaction with SDS

摘要: We describe the associative behavior of a strictly alternating comblike amphiphilic polymer in aqueous surfactant (sodium dodecyl sulfate (SDS)) solutions. The contains normal stearyl pendent hydrophobic groups separated by poly(ethylene glycol) (PEG) molecular weight 8000. average number hydrophobes per chain is 9. In dilute regime presence very low amount SDS, associates mainly flowerlike micelles similar to those formed sample structure but lower degree polymerization (on average, two three chain). Further addition SDS leads formation mixed decreasing NR (number from micelle). Flowerlike conformation preserved until concentration which coincides with critical aggregation (cac) oxide) (PEO), after disrupted. absence below overlapping concen...
