Melting temperature of trans‐polyoctenamer

Abstract The effect of microstructure on crystallizability of polyoctenamers prepared by R3Al‐WCl6 catalyst was studied. The results indicate that polyoctenamers with a broad range of trans‐vinylene content do crystallize. The measured melting points are dependent on the trans‐vinylene content. From the dependence of melting temperature on copolymer composition, a value of 73 ± 2°C. for the melting point and a molar heat of fusion ΔHu of 3520 cal./mole are calculated for 100% trans‐polyoctenamer. From the melting point depression in the presence of diluent, a value for ΔHu of 4800 cal./mole is obtained.
