PM504 ANALYSIS AND CHARACTERISATION OF POLYMERS
UNIT I
Identification and Analysis: Identification of rubbers and plastics by simple physical methods; by chemical analysis, application of instrumental techniques for identification of polymers and additives.
Thermoplastics – melting point, density, viscosity, melt flow index, K-value.
Thermosets – moisture analysis, particle size, apparent density, spiral flow test, cupflow test, gel time and peak exothermic temperature.
UNIT II
Specifications, Quality control and processability tests: Rubber latex and dry rubber – cup viscosity, total alkalinity, total solids, dry rubber content, volatile matter, KOH number, mechanical stability and heat stability, plasticity retention index (PRI), scorch time and cure characteristics (plastimeter, Mooney viscometer, oscillating disc rheometer)
Resins – acid value, hydroxyl value, isocyanate index, epoxy equivalent
UNIT III
Molecular Characterization of Polymers: Determination of molecular weight, viscometry, end group analysis, colligative property, osmametry, light scattering technique, determination of molecular weight and molecular weight distribution, gel permeation chromatography.
UNIT IV
Thermal Analysis of Polymers: Differential thermal analysis (DTA), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), thermomechanical analysis (TMA), dynamic mechanical thermal analysis (DMTA).
UNIT V
Physical Methods of Analysis: Concept of chain orientation – uniaxial and biaxial orientation, X-ray diffraction (Wide angle and small angle), neutron scattering, Infrared spectroscopy (IR & FTIR), Nuclear magnetic resonance spectrometer (NMR), GC – Mass spectrometer, optical microscopy, electron microscopy, transmission electron microscopy.
