OBJECTIVE
Students have studied the fundamentals of plastics from the point of structure and
properties. In this course the rheological aspects of production should be understood in
detail.
UNIT I INTRODUCTION TO POLYMER RHEOLOGY 9
Rheology- Classification of fluid behaviour – Elastic , viscous and viscoelastic –
Newtonian and non-newtonian fluids – Pseudo plastic and dilatant fluids – Stress, strain
– Rate of strain/shear – Relation between them – Viscosity of Polymer Systems – MFI.
81
UNIT II PRINCIPLES OF POLYMER RHEOLOGY 9
Rheological systems – Plasticity – Elastic behaviour – Stress strain curves – Viscoelastic
behaviour of polymer melts – Bingham plastic fluids – Viscoplastic fluids – Thixotropic &
Rheopectic – Viscoelastic fluids – Weissenberg effect – Die swell
UNIT III FACTORS INFLUENCING POLYMER RHEOLOGY 9
Physical factors – Effect of Temperature – Pressure – Shear rate – Shear stress – Shear
induced crystallization – Molecular Parameters – Molecular weight – MWD –
Concentration – Crosslinking – Crystallinity – Copolymerization – Grafting – Branching-
Blending -Fillers – Plasticizers – Ionic Polymers.
UNIT IV RHEOMETRY AND TESTING METHODS 9
Rheological measurements – Capillary viscometer – Rotary rheometer – Cone & Plate
(C-P), Plate-Plate (P-P) and concentric cylindrical viscometer – Static and Dynamic
Tests – Mechanical models of viscoelastic systems – Maxwell & VOIGT Kelvin –
Polymer Viscoelasticity.
UNIT V RHEOLOGY IN PLASTICS AND RUBBER PROCESSING 9
Rheology of two roll mill & calendar – Internal mixer – Extrusion – Rubber extruders –
Vented & Co-extrusion – Moulding & Forming operations – Injection, Compression,
Blow, Film Blowing, Sheet Extrusion – Melt flow through dies – Die well – Melt fracture.
