Asymmetric Polymerization

Project No.:410-25-95
Start date:1995-01-01
End date:2002-12-31
Division:Polymer Division
Objective:

Many optically active polymers have been synthesized through asymmetric polymerization reactions from optically inactive monomers. The basic definitions of terms relating to polymerization reactions have been published in IUPAC documents, but no explicit reference has been made to reactions involving the asymmetric synthesis of polymers. As a result, several names have been used for the same type of industrially-important asymmetric polymerization processes and this leads to confusion and prevents a better understanding of asymmetric polymerizations. The aim of this document is to define unified terms relating to polymerization processes which involve chirality and which proceed in an unsymmetrical manner under the influence of chiral features present in monomer, initiator, catalyst and solvent.

Description:
No description available.
Progress:
A new draft was prepared by the Working Party after the discussionat the Geneva meeting of the Commission in 1997 and was thoroughlydiscussed at the Sydney meeting in 1998, with particular emphasison the consistency with organic-chemistry nomenclature and correctEnglish. A new version was prepared by the Working Party after consultationwith authorities on asymmetirc polymerisation. The final versionwas discussed and approved in Berlin and is being sent out to OutsideExperts in September, 1999.

A revised document is submitted to public review comments until30 April 2001
