    摘要: Polyarylates having amide terminal groups are prepared using a terminating amount of ammonia, ammonium compounds, primary amines, secondary amines, hydrogen ammonium salts of secondary amines, or hydrogen ammonium salts of primary amines. These amide terminated polyarylates exhibit improved thermal properties and are useful in the production of films and molded articles.
