Abstract
Hyperbranched copolymers of hydroxyl-terminated hyperbranched poly(phenylquinoxalines) (HT-HPPQ) and fluorine-terminated hyperbranched poly(phenylquinoxaline) (FT-HPPQ) were prepared from self-polymerizable AB and AB 2 monomers and BA and BA 2 monomers. The solubility, solution viscosities, glass transition temperature and thermal stabilities varied depending on AB 2 unit contents in the copolymers. The thermal stabilities were heavily affected by kinds of surface groups. The melt viscosity decrease of hyperbranched PPQ compared to linear analog was less than expected due to the formation of hydrogen bonding in the melt.
