Differential scanning calorimetry (DSC), atomic force microscopy (AFM), 1H nuclear magnetic resonance (NMR), one-and two-dimensional fourier transform infrared spectroscopes (FTIR), size exclusion chromatography (SEC), dynamic light scattering (DLS), viscosity analyses have been used to investigate the miscibility behavior, specific interactions and supramolecular structures of poly(vinylbenzyl thymine-co-butyl methacrylate) (PVBT-co-PBMA, T-PBMA) blending with poly(vinylbenzyl adenine-co-styrene) (PVBA-co-PS, A-PS) through multiple hydrogen bonding complex upon varying the vinylbenzyl thymine and vinylbenzyl adenine contents in DNA-like copolymers.
We describe FTIR and 1H NMR spectra reveal that hydrogen bonding between VBA and VBT exclusively. In addition, viscosity measurement, SEC, and DLS provide the formation of supramolecular network structure in this binary blend system. A miscibility window exists when the vinylbenzyl thymine and vinylbenzyl adenine fraction in the copolymer is greater than 11 mol% in the A-PS/T-PBMA blend system, as predicted using the Painter¡VColeman association model.
