Copolymérisation du dicyanure de propène‐1 ylidène‐1 avec l'acétate de vinyle et des styrènes substitutés. Calcul des taux de réactivité et étude de l'effet pénultième

Abstract
1‐Propen‐1‐ylidene dicyanide was copolymerized in bulk with vinyl acetate and five substituted styrenes. The reactivity ratios of these copolymerizations were calculated by the Fineman‐Ross or the Kelen‐T¨︁udős method. The penultimate model describes satisfactorily the deviation from the terminal model in the copolymerization reactions between 1‐propene‐1‐ylidene dicyanide and the substituted styrenes.
