Fig. 9. Melting kinetics and crystallization kinetics of polymeric selenium (right) and polyethylene (left). The equilibrium melting temperatures are 494.2 and 414. 6K. The dotted curve indicates that on crystallization of the macromolecule from small molecules Sc2 there is no molecular nucle-ation necessary as in the melt crystallization (see also ref. 43 for a more detailed discussion of Se crystallization and melting). Drawn after Ref. 4,)...

The notion of gas or melt kinetic studies, free from diflfusional restrictions, is attractive, but experiments by Briggs et al show that if the composition of the feed to the second stage of a two-stage reactor system is cycled the catalyst will absorb sulphur trioxide over a period of several minutes, and this sulphur trioxide can be desorbed by blowing air over the catalyst. It is also claimed by Unni that higher conversions are possible using periodic rather than steady-state operation, an observation which may have important industrial applications.

Thermodynamics and kinetics are the two most fundamental theoretical aspects of polymer crystallization. Thermodynamics addresses why, or under which circumstances, polymer crystallization will begin, or in the opposite direction polymer crystals will start to melt. Kinetics addresses how fast polymer crystallization will be initiated, be developed, and be further improved. Both aspects decide crystal morphologies that eventually influence the properties of polymer materials.

Fundamental to understanding the crystallization behavior of polymers, whether the interest be melting, kinetics or morphology, is knowledge of the equilibrium melting temperature. The...
