Surface segregation of end-functionalized homopolymers in a homopolymer matrix

Surface segregation of end-functional poly(2-vinylpyridine) in a blend with P2VP was measured by X-ray photoelectron spectroscopy. A series of chain end functionalized P2VP homopolymers were synthesized \textit{via} either anionic polymerization or Reversible Addition Fragmentation Chain Transfer RAFT and end capped with either a single fluorinated oligomer or a perfluorinated dendrimer. The degree of end functionalization was characterized using NMR spectroscopy, IR spectroscopy and gel permeation chromotagrophy (GPC).
