Based on segregation data, determined with profiling techniques, we analyze surface phase diagram of binary liquid mixtures composed of random olefinic copolymers. Blends with extended‐ and small‐critical point wetting regimes are discussed. First observation of wetting transition is presented. Surface enrichment‐depletion duality, a phenomenon prerequisite to the 2 nd order wetting transition, is described.
