PIXE analysis of trace amount of chlorine in copolymers

Abstract

PIXE method was used the first time in the analysis of copolymers. The results showed that the chlorine content in the copolymer is less than 1 ppm and no chain transfer reaction was taken place while sample of F40 which have already been confirmed to have chain transfer reaction in F-113 was analysed and the chlorine content was found to be as high as 700 ppm.

Key words: CHLORINE, COPOLYMERS, TRACE ANALYSIS, SULFONIC ACID, TETRAFLUORO ETHYLENE, FREON, ACYL FLUORIDES, FLUOROCARBON, X-RAY FLUORESCENCE SPECTROMETRY

CLC Number:

O657
