Recording Polarized Light Photometer and Its Application to the Transition Phenomena of Several Polymers

Abstract

For observation of the transition phenomena in polymers, simple heating photometer was made. The main part of this instrument is set up from the light source with sensitive stabilizer, polarizer, cadmium sulfide photo-conductive cell and the furnace.
Then the results are recorded automatically on the strip chart paper. It can be used to the following purposes;
1) Observation of the melting behaviour in crystalline polymers.
2) Observation of the isothermal crystallization process.
3) Determination of the glass transition in amorphous polymers.
