Degradation Heterochain Polymers in the Presence of Phosphorus Stabilizers

The thermal stability and thermal stabilization of the heterochain polymers were investigated. Analysis of PAI, PSF, PEI degradation and stabilization has allowed an approach to be developed to aid their processing and resolve similar problems with other resins such as polyethersulfone, LCP, etc. Ad...

Description
Summary:The thermal stability and thermal stabilization of the heterochain polymers were investigated. Analysis of PAI, PSF, PEI degradation and stabilization has allowed an approach to be developed to aid their processing and resolve similar problems with other resins such as polyethersulfone, LCP, etc. Addition of PCA inhibits in heterochain polymers thermal oxidation at high and low temperatures.
