Kinetic Analysis of Thermogravimetry. Part 3. Experimental Modifications

Abstract

The experimental apparatus for temperature programmed thermogravimetry has been modified to more effectively obtain kinetic parameters for the degradation of polymers. The thermobalance was modified to incorporate direct sample temperature measurement thereby to minimize temperature measurement errors. An automatic data acquisition system was incorporated into the apparatus and appropriate computer programs to handle the magnetic tape data were written. The modified apparatus has been tested with styrene-acrylonitrile copolymers and it was demonstrated that the use of the magnetic tape recording system permitted greatly increased output from the thermobalance.
