Divinyl Ether-Maleic Anhydride (Pyran) Copolymer used to demonstrate the Effect of Molecular Weight on Biological Activity

Abstract

DIVINYL ether and maleic anhydride form a 1:2 copolymer, which is reported to have the structure shown here1. It is commonly known as pyran copolymer, although we prefer to call it DIVEMA, an acronym for divinyl ethermaleic anhydride. It has been designated as NSC 46015 by the National Cancer Institute.
