    • Challenging isodimorphism concepts: formation of three crystalline phases in poly(hexamethylene-ran-octamethylene carbonate) copolymers 

      Liao, Yilong; Sardon, Haritz; Pérez-Camargo, Ricardo; Martínez de Ilarduya Sáez de Asteasu, Domingo Antxon; Hu, Wenxian; Liu, Guoming; Wang, Dujin; Müller, Alejandro Jesús (American Chemical Society (ACS), 2023-10-11)
      Article
      Open Access
      In this work, poly(hexamethylene-ran-octamethylene carbonate) copolycarbonates were synthesized by melt polycondensation in a wide range of compositions. The copolymers displayed some of the characteristic isodimorphic ...

    • Disappearance of melt memory effect with comonomer incorporation in isodimorphic random copolyesters 

      Sangroniz, Leire; Safari, Maryam; Martínez de Ilarduya Sáez de Asteasu, Domingo Antxon; Sardon, Haritz; Cavallo, Dario; Müller, Alejandro Jesús (American Chemical Society (ACS), 2023-09-21)
      Article
      Open Access
      Melt memory effects in polymer crystallization have attracted much attention in the past few years. Although progress has been made in understanding how the chemical structure of polymers can affect melt memory, there are ...

    • Organocatalysis for depolymerisation 

      Jehanno, Coralie; Pérez Madrigal, Maria del Mar; Demarteau, Jeremy; Sardon, Haritz; Dove, Andrew (2019)
      Article
      Open Access
      Polymeric materials have been accumulating in the environment for decades as a result of the linear way of consuming plastics. Unfortunately, the current approaches followed to treat such a large amount of plastic waste, ...

    • Organocatalyzed closed-loop chemical recycling of thermo-compressed films of poly(ethylene furanoate) 

      Gabirondo, Elena; Melendez Rodriguez, Beatriz; Arnal, Carmen; Lagaron, Jose Maria; Martínez de Ilarduya Sáez de Asteasu, Domingo Antxon; Sardon, Haritz; Torres Giner, Sergio (2021-03-14)
      Article
      Open Access
      Monomers obtained from renewable feedstocks have emerged as a sustainable alternative to petroleum derived polymers. One of the biomass derived polyesters that has recently been gaining attention as an alternative to ...

    • ROP and crystallization behaviour of partially renewable triblock aromatic-aliphatic copolymers derived from L-lactide 

      Flores, Irma; Martínez de Ilarduya Sáez de Asteasu, Domingo Antxon; Sardon, Haritz; Müller, Alejandro J.; Muñoz Guerra, Sebastián (Elsevier, 2020-01-05)
      Article
      Open Access
      Two series of partially biobased ABA triblock copolyesters were successfully prepared by ring-opening polymerization (ROP) of L-lactide initiated by two telechelic polyester polyols using an organic catalyst. B blocks were ...

    • Synthesis of aromatic–aliphatic polyesters by enzymatic ring opening polymerization of cyclic oligoesters and their cyclodepolymerization for a circular economy 

      Flores, Irma; Martínez de Ilarduya Sáez de Asteasu, Domingo Antxon; Sardon, Haritz; Müller, Alejandro; Muñoz Guerra, Sebastián (American Chemical Society (ACS), 2019-03-08)
      Article
      Open Access
      Cyclic oligomers of hexamethylene furanoate and hexamethylene terephthalate were obtained from 1,6-hexanediol and the corresponding methyl esters using Candida antarctica lipase B (CALB) enzyme catalyst. HPLC, MALDI-TOF ...

    • Synthesis, structure, crystallization and mechanical properties of isodimorphic PBS-ran-PCL copolyesters 

      Safari, Maryam; Otaegui, Itziar; Aramburu, Nora; Guerrica-Echevarria, Gonzalo; Martínez de Ilarduya Sáez de Asteasu, Domingo Antxon; Sardon, Haritz; Müller, Alejandro J. (Multidisciplinary Digital Publishing Institute (MDPI), 2021-07-09)
      Article
      Open Access
      Isodimorphic behavior is determined by partial inclusion of comonomer segments within the crystalline structure and arises from the comparatively similar repeating chain units of the parental homopolymers. Isodimorphic ...
