✦ Synopsis

A~traet--The results obtained in a study of the heat and entropy of fusion, and a few data on the crystallization kinetics, of poly-/3-propiolactone and poly-@caprolactone are reported. Attention is focused on the entropy data for the two polymers. A comparative, theoretical analysis of the constantvolume entropy of melting of the polylaetones and of three aliphatic polyesters is made. The remainder of the entropy of melting of the polymers considered is qualitatively correlated with chemical constitution and crystal structures.
