Abstract
Donor (or acceptor) poly(carbonate)s or poly(phthalate)s were prepared from 2-(p-dimethylaminobenzyl)-1,3-propanediol (or from 2-(3,5-dinitrobenzyl)-1,3-propanediol). The spectral, thermal, mechanical, and optical properties were measured for the donor polymers, the acceptor polymers, and their blends in order to clarify the effects of the formed electron-donor-acceptor (EDA) complexes. The donor and acceptor polymer blends were found to consist of two-phase structures by differential scanning calorimetry, torsional braid analysis, and scanning electron microscopy. It was noticed that the tensile modulus of the polymer blends was larger than that of each component polymer. The increased mechanical strength was interpreted in terms of the EDA interaction on the boundaries between globules and surroundings.
