Network polymers based on 3,3-bis-(4′-hydroxyphenyl)phthalide and [2.2]paracyclophane-4,16-dicarboxylic acid

A linear ester is synthesized on the basis of phenolphthalein and [2.2]paracyclophane-4,16-dicarboxylic acid dichloride. The formation of network polymers via the heat treatment of this ester in a wide temperature range is studied. The physical properties of these polymers are investigated. The computer-aided simulation of several physical parameters (including the glass-transition temperature and the dielectric constant) is performed for both the linear polymer and feasible network structures. There is a good correlation between the experimental results and the calculated data.
