Kinetics of non-isothermal diffusion studied by mass spectrometric thermal analysis

Potential of pyrolytic mass spectrometry as a method for studying diffusion of low-molecular-weight compounds in multicomponent polymeric systems within a broad temperature interval has been explored using the system dimethylformamide-water-copolymer prepared by polycondensation of isophthalic acid...

Description
Summary:Potential of pyrolytic mass spectrometry as a method for studying diffusion of low-molecular-weight compounds in multicomponent polymeric systems within a broad temperature interval has been explored using the system dimethylformamide-water-copolymer prepared by polycondensation of isophthalic acid with m- and p-phenylenediamines as an example. The method can be used for determining the residual content of solvents in polymeric materials.
