Syllabus:

(Part A) Introduction to Plastics and Rubbers - history, classification, advantages/disadvantages, uses. Polymer Chemistry and Structure - polymerisation reactions, structures. Ingredients of Plastics and Rubbers - resins, additives, reinforcements, fillers. Properties of Plastics and Rubbers - electrical, optical, thermal and mechanical properties, flammability. Forms of Plastics - adhesives, films, foams, filaments and fibres, coatings, composites. Production Techniques - moulding, extrusion, laminating. Health and Safety - hazards, toxicity, waste pollution, recycling. (Part B) Composites - particle-reinforced composites, fibre composites.

Unit Outcomes:

On successful completion of this unit students will understand the role of chemical structural characteristics that affect the physical and mechanical properties of polymeric materials and composites. They will be able to describe a typical polymer molecule in terms of its chain structure and how the molecule may be generated by repeating mer units, draw mer structures of some common thermoplastics, thermosets and rubbers and describe addition and condensation polymerisation mechanics. This unit will allow them to cite the general characteristics of polymers, composites and their applications and name the various types of polymer additives and how they modify the properties of plastics and composites. Students will be able to describe how the density, stiffness, strength and ductility of semicrystalline polymers are influenced by the degree of crystallinity and explain the influence of polymer chemistry on melting and glass-transition temperatures. Finally they will have gained an understanding of the health and safety issues when dealing with plastics, rubbers and plastics and comprehend the problems of environmental and waste pollution and recycling of polymers.
