Prepn. and characterization of 3 high mol. wt. iptycene-contg. polybutadienes as well as their starting monomers (derived from anthracene, tetracene, and 1,4-anthraquinone via initial Diels-Alder reactions followed by operations such as hydrogenation, dehydrohalogenation, and dehydration) are described. All monomers at least possessed a butadiene unit that was used for radical polymn. leading to polymers presenting an internal free vol. that could be utilized for the enhancement of miscibility and redn. of phase sepn. in polymer blends.
