Course Content

POLYMER TYPES & NATURE

0.25 day

  • Polymer constitution: monomers, macromolecules, building blocks.
  • Various kinds of polymer: fibers, elastomers, plastics.
  • Plastic types: thermoplastics and thermosets.
  • Main commodity plastics: polyethylenes, polypropylenes, polystyrenes and polyvinylchloride.
  • Economical aspects relating to these commodity plastics.

POLYMER PRODUCTION - ASSOCIATED PROPERTIES

1 day

  • Main polymerization reactions: polyaddition, polycondensation.
  • Basic characteristics of polymer reactions: heat of reaction, activation mode, etc.
  • Different arrangements of monomer building blocks in polyaddition: atactic, syndiotactic or isotactic polymers; random block; graft; alternate polymers.
  • Relationship between end uses implementation and main polymer properties. Impact on properties.
  • Main tests used to get polymer characterization: melt index, viscosity index, etc. Test signification, relationship with polymer structure.
  • Consequences regarding polymer implementation techniques (extrusion, injection, etc.).

POLYMERIZATION IMPLEMENTATION - MAIN COMMODITY PLASTIC PROCESSES

1.75 days

  • Techniques implemented to produce polymers: solution, bulk emulsion, suspension, gas phase techniques.
  • Advantages and drawbacks of those different techniques consequences on processes implementation.
  • Examples applied to main processes used to manufacture major thermoplastics: polyethylenes (PE), polypropylenes (PP), polystyrenes (PS) and polyvinylchloride (PVC).
  • Flow charts and principles of processes. Some common and average operating conditions.
  • Influence of operating parameters (temperatures, pressures, monomers ratio and proportion of any chemicals involved in the reaction) regarding the quality of polymer obtained.
  • Some pretreatments of polymers outside the reactor before the transformation step.
Ways & Means
  • Presentation of plastics sample from plants.
  • Presentation of end uses application samples.
