| Summary: | Includes abstract. === Includes bibliographical references (leaves 157-163). === The differential scanning calorimetry (DSC) analyses of the Fischer-Tropsch (FT) hard waxes display multiple melting peaks, the origin of which is unknown. The phenomenon is sometimes referred to in the literature, but no attempt has been made to explain its cause. There are a few known causes of melting bimodality in n-alkanes and their mixtures, petroleum waxes and polymers. These are: polymorphism, chain folding and bimodal molecular weight distributions |
