Interfacial Properties of Miktoarm Star Polymers with a Poly(divinylbenzene) Core.

ABSTRACT: The interfacial properties of miktoarm star polymers composed of poly(divinylbenzene) (PDVB) cores with poly(ethylene oxide) (PEO) hydrophilic arms and poly(n-butyl acrylate) (PBA) or poly(lauryl acrylate) (PLA) hydrophobic arms at the oil/water interface are reported. The kinetics of miktoarm star polymer adsorption from the oil phase depended on the polymer concentration. This suggested that the rate-determining step was the adsorption and penetration of the polymer onto and through the interface. This was attributed to the desolvation of the polymer arms from the oil phase being less facile than that of similar star polymers with PEO arms alone from the aqueous phase. PEO star polymers showed diffusion-controlled kinetics, and as such, the adsorption and so forth were facile and
