Design Chemical Structures of CO2-Derived Poly(cyclohexene carbonate) Copolymers to Mediate Intra-/Intermolecular Interactions with Strong Hydrogen-Bonded Donor Homopolymer
The ring opening copolymerization (ROCOP) of CO2-based poly(carbonate-co-ester) (PC-co-PE) copolymers was synthesized by cyclohexene oxide (CHO), anhydrides (AH), and carbon dioxide (CO2) with various contents of AH. Herein, phthalic anhydride and 1,2-cyclohexanedicarboxylic anhydride were chosen for prepared poly(cyclohexene carbonate-co-cyclohexane carboxylate) (PCHC-CHA) and poly(cyclohexene carbonate-co-phthalate) (PCHC-PA). Polycarbonate-co-polyester and polyester copolymers possess strong intramolecular H-bonding interactions on the polycarbonate (PC) or polyester (PE) segments, which was confirmed by two-dimensional Fourier transform infrared (2D FTIR) spectroscopy analyses. Compared to the PC segment, the OH units of poly(vinylphenol) (PVPh) preferred to form intermolecular hydrogen bonding with the polyester segment and possess a higher intermolecular association equilibrium constant (KA). The trend of intermolecular H-bonded strength was PVPh/PE-CHA > PVPh/PCHC-CHA > PVPh/PCHC-PA > PVPh/PCHC binary blends. Adjusting the PC % and PE % could improve the intra-/intermolecular hydrogen bonding ratio on the PVPh/PC-co-PE binary blend, which could be observed in the change of the q value (q value generally corresponds to the H-bonding strength of the miscible polymer blend based on the Kwei equation) from DSC analyses.
期刊介绍：
Macromolecules publishes original, fundamental, and impactful research on all aspects of polymer science. Topics of interest include synthesis (e.g., controlled polymerizations, polymerization catalysis, post polymerization modification, new monomer structures and polymer architectures, and polymerization mechanisms/kinetics analysis); phase behavior, thermodynamics, dynamic, and ordering/disordering phenomena (e.g., self-assembly, gelation, crystallization, solution/melt/solid-state characteristics); structure and properties (e.g., mechanical and rheological properties, surface/interfacial characteristics, electronic and transport properties); new state of the art characterization (e.g., spectroscopy, scattering, microscopy, rheology), simulation (e.g., Monte Carlo, molecular dynamics, multi-scale/coarse-grained modeling), and theoretical methods. Renewable/sustainable polymers, polymer networks, responsive polymers, electro-, magneto- and opto-active macromolecules, inorganic polymers, charge-transporting polymers (ion-containing, semiconducting, and conducting), nanostructured polymers, and polymer composites are also of interest. Typical papers published in Macromolecules showcase important and innovative concepts, experimental methods/observations, and theoretical/computational approaches that demonstrate a fundamental advance in the understanding of polymers.
