The stress strain curves of a set of gutta percha fractions with broader molecular weight distribution were investigated,the transition of gutta percha from brittle to plastic,and then to dutile was revealed with the change of its molecular weight,and the molecular weight range,responding to which gutta percha transited from brittle to plastic,was established.
