State of Art of polymer Research in India. Part III. Physical chemistry of polymers

Abstract

Work on dilute solution properties as well as thermal, electrical, mechanical and photo-chemicaI prorertics of polymers from more than fifty institutions in India during the past about four decades has been reviewed. Various techniques like Viscosity, osmosis, light scattering, DSC, TGA, DTA, UV, IR, NMR, mass spectrometry, X-ray diffraction, SEM, etc. were employed. Thermodynamic parameters of polymer molecules have been evaluated: structure-reactivity, mechanisms for degradation, etc. have been suggested. Reacior designs for various types of polymerization, crystallization, vulcanization, blending of polymers have been covered. In the concluding paragrarh a few suggestions for future work have been made.
