Crystallization Kinetics and Polymorphic Transformations in Polybutene-1. [PDF]
J Res Natl Bur Stand A Phys Chem, 1965 When subcooled from the melt to any temperature between about 90 to 110 °C, polybutene-1 transforms at a readily measurable rate to a crystalline phase denoted "form 2," which is typically spherulitic. The kinetics of this process have been measured by optical and dilatometric techniques. The results are consistent with the concepts that the initiation
