Polymer nomenclature weight average

Subsequently we show some important properties of the moment generating function. This include the number and weight average of the degree of polymerization and other averages, as well as the distribution function. There is a potential confusing situation in nomenclature. In polymer chemistry, the term cumulative distribution is used for what is called in mathematics the cumulative distribution function or simply distribution function. Further, polymer chemistry uses the term differential distribution for the mathematical term probability density function. 

The prediction of conversion, the range in which the values for number average and weight average molecular masses and the values for polydispersity are expected to lie are presented. In addition a comparison of the model results with the experimental data for the chosen polymer-initiator system is described. Finally the influence of benzoyl peroxide as the initiator in the polymerization of styrene can be compared with other initiator influences such as azo-bis-isobutyronitrile (AIBN) and bis-4-t-butylcyclohexyl peroxydicarbonate (Perkadox 16) reported by other researches (Villermaux and Blavier 1984). The nomenclature for all relationships in the following three sections is given in the Nomenclature chapter.
