Summary

Blends of donor-macromolecules — poly(N-(2-hydroxyethyl)-carb-azolyl)methacrylate — with acceptor-macromolecules — poly(methacryloyl-β-hydroxyethyl-3,5-dinitrobenzoate) — exhibit unique dynamic mechanical properties over a broad range of frequency and temperature when compared with those of the components. The complexation between the unlike polymers determines the topology of the thermoreversible network. Plateau modulus is extended into the low frequency and high temperature region dramatically. Corresponding copolymers show up minor improvement of the properties only depending on the donor-acceptor ratio within the macromolecular chain. Thus, the efficacy of intermolecular thermoreversible crosslinking clearly is evidenced.
