    Furanic polyesters, derived from renewable 2,5-furandicarboxylic acid, are highly attractive polymers and sustainable substitutes of some performance-related fossil-based commodities like polyethylene terephthalate. In this work a new synthetic pathway for the production of furan-based polyesters is reported. Cyclic oligoesters of 2,5-furandicarboxylic acid and butane diol are chemically synthesized by semi-batch esterification. The cycles are then successfully polymerized via ring-opening polymerization.

  2. Partial Molar Volumes and Thermal Expansion Coefficients as an Explanation for Co-Solvent Effect of Penetrants in Multicomponent Polymer Mixtures

    For multicomponent gases/polymer mixtures, partial molar volume and volumetric thermal expansion coefficient of each gas dissolved in the polymer phase are estimated by using the experimental solubility or swelling data in conjunction with the Sanchez–Lacombe equation of state. The results suggest that the co-solvent effect is provoked by the gas with higher solubility and higher volumetric thermal expansion coefficient.

  3. Copolymerization of N-(prop-1-yne-3-yl)-4-(piperidine-1-yl)-1,8-naphthalimide with Arylacetylenes into Fluorescent Polyacetylene-Type Conjugated Polymers

    Radoslava Sivkova, Olga Trhlíková, Jiří Zedník and Jan Sedláček

    Article first published online: 12 OCT 2015 | DOI: 10.1002/macp.201500240

    1,8-naphthalimide containing polyacetylene-type copolymers possessing either linear or cross-linked architecture and microporous texture are prepared by one-step polymerization. Copolymers exhibit fluorescence upon excitation of 1,8-naphthalimide directly or via energy transfer.

  4. Multicyclic Polyesters of Trimesic Acid and Alkanediols and the Theory of Network Formation

    Hans R. Kricheldorf, Steffen M. Weidner and Mohammed Lahcini

    Article first published online: 12 OCT 2015 | DOI: 10.1002/macp.201500245

    Depending on the reaction conditions, polycondensations of trifunctional monomers yield soluble nanogels or insoluble networks. At moderate monomer concentrations the initially formed functional cyclic and multicyclic oligomers (the “eggs”) serve as building blocks for the larger nanogels or networks. Polycondensations in bulk yield at first hyperbranched oligomers and polymers (the “hens”) which form small cyclic units in a later stage of the polycondensation.

  5. One-Pot Combination of eROP and ROMP for the Synthesis of Block Copolymers

    Wei Jiang, Ni An, Qiuping Zhang, Shidong Xiang, Zhenguo Bai, Haobo Han, Xuesong Li, Quanshun Li and Jun Tang

    Article first published online: 9 OCT 2015 | DOI: 10.1002/macp.201500313

    The one-pot combination of eROP and ROMP is successfully conducted to prepare block copolymers. The strategy possesses many advantages for preparing well-defined copolymers, such as mild reaction conditions and the elimination of purification steps for complex intermediates.
