Abstract: Amphiphilic copolymer mol. brushes of three different types with side chains consisting of alkyl and oligo(ethylene glycol) blocks based on higher alkoxy oligo(ethylene glycol) methacrylates (HAOEGM), methoxy oligo(ethylene glycol) methacrylates (MOEGM) and dodecyl(meth)acrylate have been successfully synthesized via conventional radical polymerization in toluene. In case of the copolymerization of HAOEGM with MOEGM, the monomer reactivity ratios were independent of the structure of higher alkyl groups (C12-C18) and the degree of ethoxylation (n = 6-11) and were equal to 0.76-0.81 and 1.19-1.27, resp. In case of the copolymerization of HAOEGM or MOEGM with dodecyl methacrylate, the reactivity ratios were even closer to each other (1.00-1.17). Applicability of the reactivity ratios calculated at low conversions for estimating copolymer compositions at high conversions was shown. In all systems, compositionally homogeneous copolymers with a narrow mol. weight distribution were formed. For the HAOEGM (C12, n = 9)-dodecyl acrylate monomer system, the reactivity ratios were 0.88 and 0.25 and the resulting copolymers had high compositional heterogeneity.
