Double hydrophilic copolymers (PEG-b-PCDs) with one PEG block and another block containing β-cyclodextrin (β-CD) units were synthesized by macromolecular substitution reaction. Via a dialysis procedure, complex assemblies with a core–shell structure were prepared using PEG-b-PCDs in the presence of a hydrophobic homopolymer poly(β-benzyl l-aspartate) (PBLA). The hydrophobic PBLA resided preferably...
The influence of a polar plasticizer glycerol, and a nonpolar plasticizer, dioctylphthalate (DOP), on the microstructure and relaxation properties of poly(methyl methacrylate) ionomers has been investigated by dynamic mechanical thermal analysis. The test results indicate that glycerol strongly interacts with and weakens the ionic cluster ‘phase’, and also significantly increases the mobility of backbone...
The influence of ion content and ionomer morphology on deformation modes of poly(styrene-co-sodium methacrylate) ionomers has been examined. Dynamic mechanical thermal analysis indicates a morphology characteristic to amorphous ionomers: two separate loss peaks are observed, one associated with the glass transition of the multiplet-containing matrix phase and the higher temperature loss peak with...
