Data on the influence of crystallization on the mechanical 
properties of elastomers <197> the elastic modulus, the relaxation 
properties, in particular, restorability in compression, and the tensile 
strength - have been generalized. These data have been compared 
to those on the influence of active fillers and a much higher crystallization 
efficiency has been shown. The size of single crystals has been evaluated 
for most crystallizable rubbers. It has been inferred that the nanosize 
of single crystals of elastomers and their direct bond with the elastomer 
matrix influence the mechanical properties of elastomer materials. 
In considering a partially crystallized elastomer as a nanocomposite 
model, one can formulate requirements imposed on efficient nanofillers 
for elastomer materials.
