Influence of Stabilizers

Influence of stabilizers on the degree of crosslinking (measured as insoluble contents) in a polyamide 6 (with crosslinking agents) [718] 

Insoluble contents (from solvent extraction) and OIT (s. Section 2.1.3.4.2) in PE as a function of the electron radiation dose [719]

Stricdy speaking this is only the case for half of the molecules in the crystal the other half have the two phenyl groups in parallel planes. This is certainly a consequence of the opposite influence of stabilization by the extra R.E. and a greater cohesion energy through better packing of the molecules in this particular lattice. 

Steatite materials may lose strength after long periods of time, as a result of slow conversion to clinoenstatite occurring even at room temperature. This effect is inhibited by a fine-grained structure and by the presence of the glassy phase, and also by the influence of stabilizers (e.g. MnO). The phenomenon is more distinct with rapidly cooled samples than slowly cooled samples.

Allen et al. (106) studied the thermal and UV degradation of PECT samples and the degradation products where characterized by fluorescence and observed the presence of mono and dihydroxytere-phthalate cromophores in the degraded samples. They also studied (107) the thermal and photochemical oxidation of PECT by chemiluminescence and evaluated the influence of stabilizers. They concluded that the hydroperoxide sites formed during oxidation were responsible for the chemiluminescence response.

First, to study the influence of stabilizer properties, such as the chain length, the amount of needed stabilizer and the binding strength, the other parameters, such as the temperature, the solvent as well as the stabilization time were kept constant. Therefore, depending on the affinity of the functional group of the stabilizer to the particle surface, TTO nanoparticles were stabilized with n-alkylamines of chain length between C5 and C12 and the stabilization of Zr02 particles occurs upon the addition of carboxyhc acids (C6 to C12).
