Application of characterisation methods for a specific problem

In section 7.2 it was shown that the differences in the viscoelastic behaviour among gum rubbers are carried into the differences among corresponding rubber compounds. The observation is semi-quantitative but it is important to demonstrate the trend. 

In section 7.3 a quantitative relationship between a gum rubber and its compound in the elongational behaviour is described in terms of strain- and strain-rate amplification. The 

In this section even more detailed questions are asked about the specific effect of branching and that of crystalline particle fillers in gum rubbers on the elongational behaviour of compounds. The filler type is also a variable. A quantitative comparison is intended in this section [27].
