Three methods are proposed for calculating melting temperature characteristics. These methods are based on: (i) average crystal size, (ii) the crystal stem number distribution function, and (iii) the monomer structural unit distribution function. They were employed to analyze the isothermal and non-...

A general model for all kinds of size-dependent melting points, free of any adjustable parameter, is extended to illustrate the size-dependence of the melting temperature of polyethylene (PE). The model prediction for the depression of the melting temperature of PE is consistent with the calorimet...

An experimental study of crystallization and melting of polyethylene and its octene copolymers under quiescent conditions and their melt-spun fibers is presented. This includes copolymers produced by both Dow's Insite Technology homogeneous catalyst and by a Ziegler heterogeneous catalyst. It is found ...
The influence of highly compressed gases on the melting of polyethylene was investigated for nitrogen, helium and ethylene. The impact of the particle size of the polymer and the heating rate on the melting point were also analysed. The melting points were determined with a high pressure different...
If the molecular weight dependence of the melting temperature for PBSu is similar to that for polyethylene, the results for the molecular weight dependence of PBSu can be explained. © 2002 Wiley Periodicals, Inc. J Polym Sci Part B: Polym Phys 40: 2411–2420, 2002 View Full Article (...
