Plastics are used in millions of applications due to their good mechanical properties, ease of manufacturing and low cost. In this video we explore the science behind these materials to provide an introduction to polymer science.

00:00 Introduction
00:08 Why are polymers important?
00:55 What is a polymer?
02:00 Chemical bonding types in polymers (Covalent bonds and van der Waals forces)
03:29 Types of polymer chains (linear, branched, crosslinked)
04:35 Crystalline vs amorphous structures
05:35 Classification of polymers (Thermoplastics, elastomers and thermosets)
06:50 Tensile properties (Chain entanglement)
07:47 Glass transition temperature
09:17 Viscoelastic behaviour
10:23 Summary
