this capacity was found not only in macromolecular synthetic polyribonucleotides such as ( poly i ) - ( poly c ) , ( poly g ) - ( poly c ) , ( poly a ) - ( poly u ) and substances with much lower molecular weight such as copolymers of vinylpyrrolidone with maleic anhydride , crotonic acid or metacrylic acid but also in a low molecular interferon inducer tiloron .
