Effects of MgAlCe‐CO3 layered double hydroxides on the thermal stability of PVC resin

“…Ca/Zn stabilizers have synergistic effect and present favorable stabilization 26, 27. Zinc stearate has strong Lewis acidity, which can scavenge HCl and react with labile chlorine atoms.…”

Some remarks on the use of isothermal thermogravimetric data for the evaluation of kinetic parameters. Applications for degradation of polymeric materials

“…The results obtained following an investigation of the isothermal and nonisothermal degradation in nitrogen flow of PVC/CPE blends of different mass fraction of polymers (100/0, 90/10, 80/20, 70/30, 50/50, and 0/100) are presented in ref 7…”

“…The results obtained for the 100/0, 90/10, and 80/20 samples are listed in Table V. The standard deviations of the activation energy values as well as the corresponding correlation coefficients of the linear regressions are not given in ref 7…”

“…The procedure allows avoiding time corrections for heating at the required temperature as well as for the induction period. This procedure was used for the kinetic analysis of some recent results6, 7 concerning (a) poly(vinyl chloride)/acrilonitrile–butadiene–styrene (PVC/ABS) blends and (b) poly(vinyl chloride)/chlorinated poly(ethylene) (PVC/CPE) blends.…”

Influence of acrylate processing aid‐based ionomer containing lanthanide (La(III)) ion on thermal stability, fusion, transparency and mechanical properties of rigid poly(vinyl chloride)

“…However, thermal degradation of PVC resulting from inherent structural defects makes it less stable than many other thermoplastics 2–6. Much attention is focused on thermal stabilizers for PVC because of their great industrial interest 2, 5–18. In the last few decades, in respect of environmental protection and health, many countries have promoted special policies to forbid the use of commonly used thermal stabilizers such as lead salt and cadmium soap because of the formation of toxic by‐products from their degradation.…”
