1. The number of publications devoted to investigation of rheological properties of polymeric substances may be as high as several thousand. Therefore, publications discussed in this chapter include, in most instances, only the most recent data. There are several monographs reviewing the current status of this field, and for those who are especially interested in polymer rheology, these monographs may be of interest. The results of many early fundamental investigations are discussed in the book: G.V. Vinogradov. A.Ya. Malkin, Rheology of Polymers, Springer, Berlin, 1980. The most recent comprehensive reviews of this subject are included in book by C.W. Macosko, Rheology: Principles. Measurements, and Applications, VCH, NY, 1994.
2. Elastic Behaviour of some Polymer Melts
3. This effect is well documented for metallocene-catalyzed polyethylene, see e.g., E.E. Bin Vadud, D.G. Baird, J. Rheol., 44, 1151 (2000).
4. Melt rheology of randomly branched polystyrenes
5. Characterization of long chain branching: Dilution rheology of industrial polyethylenes
