Introduction to polymers

This unit examines the use of polymers and demonstrates how the properties of polymers are controlled by their molecular structure. You will learn how this structure determines which polymer to use for a particular product. You will also explore the manufacturing techniques used and the how the use of polymerisation can be used to control the structure of polymers.
After studying this unit you should be able to:
- isolate the key design features of a product which relate directly to the material(s) used in its construction;
- indicate how the properties of polymeric materials can be exploited by a product designer;
- describe the role of rubber-toughening in improving the mechanical properties of polymers;
- identify the repeat units of particular polymers and specify the isomeric structures which can exist for those repeat units;
- estimate the number- and weight-average molecular masses of polymer samples given the degree of polymerization and mass fraction of chains present;
- calculate the molecular mass distribution for chain and step growth polymerizations from the concentrations of reactants and degree of conversion of monomer;
- assess the effect of reactivity ratio on copolymer structures;
- relate the crystal melting point Tm and the glass transition temperature Tg to molecular parameters, particularly chain length and composition;
- interpret the mechanical properties of polymers using a viscoelastic master curve or dynamic mechanical information;
- make a preliminary selection of an appropriate polymer for a particular product specification.

Introduction to polymers
Introduction

Polymers are materials composed of long molecular chains that are well-accepted for a wide variety of applications. This unit explores these materials in terms of their chemical composition, associated properties and processes of manufacture from petrochemicals. The unit also shows a range of products in which polymers are used and explains why they are chosen in preference to many conventional materials.
This unit is from our archive and it is an adapted extract from Design and manufacture with polymers (T838) which is no longer taught by The Open University. If you wish to study formally with us, you may wish to explore the courses we offer in this subject area. [Tip: hold Ctrl and click a link to open it in a new tab. (Hide tip)]
