      abstract     = {Multiblock ethylene-1-butene copolymers (PEB-n) with graded
                      ethylene content (where n is the number of ethyl branches
                      per 100 backbone carbons) represent efficient cold filter
                      plugging point (CFPP) depressants for crude oils and middle
                      distillates. The aggregation behavior and the interaction

                      PEB-13.2 and triblock PEB-6.5/PEB-8.9/PEB-10.1 copolymers in
                      decane solutions were investigated over a wide temperature
                      range by combining different small-angle neutron scattering
                      techniques and optical microscopy. The experimental results
                      revealed in the decrease of temperature formation and
                      evolution of multisized structural levels showing a
                      hierarchical organization on the length scale from 1 nm up
                      to 10 mu m. One-dimensional polymer aggregates arising as
                      initial structures associate and branch that lead to the
                      occurrence of complex macroaggregates with diffusive
                      interfaces and sizes of several microns. The one-dimensional
                      copolymer structure shows longitudinal density modulation
                      and micellar-like substructures in neat polymer solutions.
                      When wax is added, this structure becomes more homogeneous
                      in decrease of temperature as a consequence of the
                      cocrystallization of wax and copolymer. The wax
                      crystallization in board-like objects of much smaller size
                      than required by the CFPP criterion of oil and refinery
                      industry (filter mesh size of 45 mu m) is templated and
                      controlled by the assembling features of the crystalline
                      amorphous PEB-n multiblock copolymers. (C) 2010 Wiley
