Abstract

Poly‐9‐vinyladenine was prepared by reaction of poly‐6‐chloro‐9‐vinylpurine with ammonia and poly‐1‐vinyluracil by hydrolysis of poly‐L‐vinyl‐2‐ethoxy‐4‐pyrimidinone. In aqueous solutions poly‐9‐vinyladenine shows hypochromism in the ultraviolet spectrum and forms a complex with polyuridylic acid as detected by a further decrease in the ultraviolet absorption. Under the same conditions, poly‐9‐vinyladenine and poly‐L‐vinyluracil interact with formation of higher aggregates.
