Abstract

This chapter introduces the fundamental concepts of radical polymerization. Typical monomers, initiators, and transfer and termination reagents are discussed. Furthermore, the kinetic equations, the degree of polymerization, and molar mass distribution are derived.

Notes

  1. 1.

    The concept of a quasi-stationary state involves the assumption that the change in the concentration of intermediate products (here P ) can be neglected when compared with changes in the concentration of educts (here M) and products (here P) (Frost and Pearson 1964)

  2. 2.

    For polystyrene methanol is a suitable non-solvent. Extensive information about solvents and non-solvents can be found, for example, in Brandrup and Immergut (1989).

  3. 3.

    During the polymerization, the Van der Waals distances between monomer molecules are replaced by covalent bonds which are shorter so that the polymer usually has a greater density than the monomers.
