“…With increasing REDMUD particles content from 5 to 15 wt.%, the T p values of LLDPE/REDMUD blends increased from those of the pure LLDPE samples, and then began to decrease as the REDMUD particles content was more than 15 wt.%. It is speculated that the nucleating efficiency of REDMUD particles on LLDPE crystallization reached a plateau level at higher concentration of REDMUD, which is consistent with others' research [22][23][24][25] .…”

The non-isothermal crystallization behaviour of pure LLDPE and LLDPE/REDMUD blends was investigated by differential scanning calorimetry (DSC), and the crystallization kinetics was analyzed by three methods, namely the Jeziorny, the Mo and the Ozawa. The results show that an optimal content of REDMUD (lower than10 wt.%) can enhance the kinetic crystallizability of the system because of heterogeneous nucleation, but excessive REDMUD, by physical hindrance, would impair the kinetic crystallizability. In non-isothermal crystallization kinetics, the Ozawa model did not fit well with the crystallization behaviour of these systems, while the Jeziorny and Mo models were found to be applicable. Furthermore, the activation energy ΔE calculated by the Kissinger method for the transport of macromolecular segments to the growing surface of crystal nucleus indicates that REDMUD could significantly reduce the crystallization migration activation energy of these blends.

This work is based on the analysis of the influence of dispersing agents on the non-isothermal kinetics, thermomechanical behaviour and dispersing action of PET/TiO 2 nanocomposites. The influence of two montanic waxes and an amide wax used as dispersing agents in the nucleating effect of the nanoparticles is studied. The dispersing agents are the following: a) a partly saponified ester of montanic acids (PSEMA), b) an ester of montanic acids with multifunctional alcohols (MAWMA) and c) an amide wax based on N,N'-Bisstearoyl ethylenediamine (AW). The non-isothermal kinetics based on the Avrami method revealed that MAWMA and PSEMA favours the nucleating effect of the nanoparticles when are included in PET. Birefringence microscopy points out the good dispersing capacity of MAWMA and AW and the termomechanical analysis confirmed that the ester of montanic acids with multifunctional alcohols MAWMA shows the best dispersing properties and best promotes the nucleating effect of the TiO 2 nanoparticles when used for PET/TiO 2 nanocomposites production.

“…So, this parameter does not represent an energy barrier to the crystallization process, it is an effective parameter, although at times it is interpreted like this. Numerous studies erroneously implemented the definition of such effective activation energy [15][16][17].…”
