Developments in polymerization,merizations, and stepwise condensation and rearrangement polymerizations, were laid during the period from 1930 to 1960. Of the mechanisms mentioned above, which we can regard as being the primary methods for the synthesis of polymers, the most recently discovered is coordination (or Ziegler-Natta)

Group transfer polymerizations, to polymers with relatively broad molecular weight distributions and allows little or no control over polymer microstructure. Scientific and commercial advantages may be gained if control can be exercised over the molecular weight and molecular weight distribution of a polymer as it is formed (espe

Group transfer polymerizations,cially if the ratio ../.. can be reduced to about unity), if tacticity can be controlled and if inherent chain termination can be avoided; the latter facilitates the synthesis of block and graft copolymers.

Transformation reactions,ge, but instead describes the use of novel termination/reinitiation chemistry, generically known as transformation reactions, which enables different polymerization techniques to be used sequentially for the production of a vastly enlarged range of AB and ABA block copolymers.

Ring-opening metathesis polymerization of cyclic alkenes,en used. Effective catalysts may be either homogeneous or heterogeneous and, although not essential as part of the catalyst system, organometallic compounds, usually either organometallic aluminium or tin compounds, are incorporated as a second component of two component catalyst systems.
