Florian Stempfle, Patrick Ortmann and Stefan Mecking Which Polyesters Can Mimic Polyethylene? Macromolecular Rapid Communications 34
Polyester-26,26, generated by self-metathesis of erucic acid, possesses the highest melting point among the long-chain aliphatic polyesters reported to date. This is underlined by model ultralong-chain polyester-38,23 (Tm = 109 °C) and polyester-44,23 (Tm = 111 °C), which show that melting points of such aliphatic polyesters do not gradually increase with methylene chain length, but will require even longer sequences to converge with linear polyethylene.
