Evaluation of mechanical and thermal properties after chemical degradation of PVC and HDPE geomembranes
(2013-06-10)
Chemical compatibility between geomembranes and site-specific waste liquids should be assessed since the waste liquids are highly complex mixtures. This paper presents some considerations about the chemical compatibility ...
New thermal study of polymerization and degradation kinetics of methylene diphenyl diisocyanate
(2018-09-01)
This work investigates the thermal polymerization process of a methylene diphenyl diisocyanate (MDI) monomer as well as its thermal degradation following the ICTAC recommendations. MDI monomer is widely used as a synthetic ...
Thermal degradation of a phenolic resin, vegetable fibers, and derived composites
(John Wiley & Sons Inc, 2008-03)
The thermal degradation behavior of resol, several vegetable fibers (two types of cotton fibers, sisal and sugar cane bagasse) and derived polymer composites have been investigated using thermogravimetric analysis (TGA). ...
Thermal degradation of poly (ε-caprolactone) nanocomposites with soy lecithin-modified bentonite fillers
(Elsevier Science, 2020-07)
Thermal degradation of green nanocomposite films prepared from poly (ε-caprolactone) (PCL) and soy lecithin (SL)-modified bentonite (Bent) obtained by melt blending were studied through thermal degradation kinetics and ...
Thermal degradation of mixtures of polycaprolactone with cellulose derivatives
(Elsevier, 2003-12)
Thermal degradation processes for a series of mixtures based on polycaprolactone (PCL), with microcrystalline cellulose (MC) and sisal fiber (SF) powder, were investigated by thermogravimetric analysis (TGA), in order to ...
Thermal degradation of geomembranes after exposure to heat
(Millpress Science Publishers, 2006-01-01)
HDPE and PVC geomembranes are sensitive to changes in their properties when in contact with high temperatures. The effects of hot temperature on polymeric geomembranes are assessed by the ASTM D794 and ASTM D5721.This paper ...

A deep investigation into the thermal degradation of urethane dimethacrylate polymer
(2021-01-01)
This work investigates in depth the thermal degradation process of a polymer of urethane dimethacrylate (UDMA). UDMA monomer has been widely used in dental restorations and biomaterials. The use of density functional theory ...
Lornoxicam drug—A new study of thermal degradation under oxidative and pyrolysis conditions using the thermoanalytical techniques, DRX and LC-MS/MS
(2019-10-01)
In the present work, the thermal behavior of Lornoxicam drug was studied under oxidizing (air) and pyrolysis (N2) atmospheres using simultaneous thermogravimetry and differential scanning calorimetry (TG-DSC), differential ...
Impact of different nanoparticles on the thermal degradation kinetics of phenolic resin nanocomposites
(Springer, 2017-01-30)
The effect of different contents of nano-fillers: carbon black (CB), bentonites (original (Bent) and modified with phosphonium salt (B-TBHP)) and commercial modified montmorillonite (C30B) on the thermal degradation of ...
