Stepwise linear magnetic polymers and methods for preparation thereof

摘要

A stepwise linear polymer composition having intense magnetic properties and a method for preparation of same. A phthalimide compound and an aromatic dialiphatic acid are reacted in the presence of an acetate of monovalent metal at elevated temperatures to form a phenylenebis diphthalimidine compound. The phenylenebis diphthalimidine compound is then reacted with 3-benzylidine phthalimidine and a metal salt of an aliphatic acid at elevated temperatures under an inert gas to form the intensely magnetic polymer. The reactions may be carried out in the presence of a solvent.
