UNIT I 8
Polymer structure – chain structure – micro structure – crystal structure crystallinity –
determination of crystallinity, size and orientation of crystallites using x-rays-conformation
and configuration- analysis of random flight chain model – application to rubber elasticity -
engineering rubbers.

UNIT II 13
Mechanical properties – deformation of plastic materials- classification of plastic materials
based on their stress – strain relationship – effect of temperature on deformation-time
dependence and viscoelasticity in solid plastics –models of viscoelasticity – Boltzmann’s
superposition principle- dynamic mechanical properties – yielding of plastics- aspects of the
yield process under tensile stress – crazing and shear yielding – yielding in semicrystalline
polymers –mechanical failure in plastics.
