ABSTRACT:
High molecular weight processible polymers derived from 2,6- and 2,7-diacids, diols and diamines of 9,10-dihydro-9,10-ethanoanthracenes and various complementary comonomers are prepared. These are converted into rigid, thermally-stable anthraceno polyesters and polyamides by thermal removal of the 9,10-ethano bridge.
