Abstract

The influence of carbon nanotubes (CNТ) on enthalpy relaxation kinetics of polymethylmetacrylate
(PMMA) is studied by the method of differential scanning calorimetry. The improved phenomenologic
model for description of the structural relaxation of amorphous polymers in the glassing
area is offered. The kinetic parameters of enthalpy relaxation for neat PMMA and nanocomposites
which contained from 0,2 to 2 % carbon nanotubes were got from calculations. The fact of the
infinite cluster formation were set from the changes of kinetic relaxation parameters. The features
of polymeric composites’ structure influence on their thermophysical properties are studied.
