When a polymer is stretched the snarls begin to disentangle and straighten out Elasticity of the polymer is mainly because of the uncoiling and recoiling.
Polymers can degrade by exposure to high temperature Shear action Oxygen, ozone and chemicals Electromagnetic ( , UV) Ultrasonic radiation Moisture Thermal.

Starter What is the difference between an addition and condensation polymer? Write an equation for the polymerisation of two molecules of 3-hydroxypropanoic.
Important Points from Last Lecture: For mixing to occur, the free energy (F) of the system must decrease; F mix < 0. At a constant T, the change in free.
