Photodegradation and photostabilization of polymers
The thermal degradation of the biodegradable bacterial polyesters poly(3-hydroxybutyrate), PHB, poly(3-hydroxyvalerate), PHV, and poly(3-hydroxybutyrate-co-3-hydroxyvalerate), 0−21 mol % of hydroxyvalerate, was studied.... The thermal and mechanical properties of the biopolymers were investigated by GPC, TGA, DSC, mechanical test, and DMA. The molecular weights of Bioflex and Solanyl showed no susceptible effect of the recycling process, however, a significant reduction was observed in the molecular weight of PLA and PHBV. The inherent thermo-mechanical degradation in PHBV and PLA resulted in 20% and 7%

Thermal degradation ppt of polymers SlideShare

From Wikipedia, the free encyclopedia. Thermal degradation of polymers is molecular deterioration as a result of overheating. At high temperatures the components of the long chain backbone of the polymer can begin to separate (molecular scission) and react with one another to change the properties of the polymer....
Thermal Degradation and Crystallisation Behaviour ,,,, Abstract In this chapter we discuss the thermal degradation and crystallisation behaviour of nylonlEPDM blends. Effects of blend ratio, compatibiliser concentration and dynamic vulcanisation on the thermal degradation of the blends are discussed in detail. The kinetic parameter of the degradation process is studied. Melting and

Thermal Degradation Of Polymers Pdf

Thermal degradation of polymeric materials is an important issue from both the academic and the industrial viewpoints. Understanding the thermal degradation of polymers is of paramount importance for developing a rational technology of polymer processing and higher-temperature applications.

  • The consequences of photo-degradation depend on the nature of the polymer and can cause polymer chain scission and cross-linking leading to changes at the molecular level.
