Abstract
A dynamic star polymer contains a plurality of at least three substantially identical block copolymers, each block copolymer including an aromatic polymer moiety having a glass transition temperature of at least about 95.degree. C., and an aliphatic polymer moiety incompatible with the aromatic polymer moiety. The aromatic moieties of each of the formed block copolymers aggregate to form a chemically uncrosslinked core, while the aliphatic polymer moieties radiate outwardly from the core. The multi-arm star polymer is uniquely capable of changing its molecular structure under external influences, and the core thereof preferably exhibits thermoplastic characteristics.
