Subcommittee on Modeling of Polymerization Kinetics
and Processes
Chairman: Prof.
Michael Buback
Secretary: Dr. Sabine
Beuermann
> List of Members
> Current Projects
>> Purpose > >> Organisation
and Projects
- To conduct characterisation studies on polymeric materials.
- To establish an interaction between scientists from Academy
and Industry in conducting such characterisation.
- To select characterisation themes that are suitable for an
IUPAC study.
- To publish/report results.
Former Organisation
The purpose of the Commission meetings is to explore ongoing strategy
and to review progress of its Working Parties, which hold their own
separate meetings at other times and locations.
The Working Parties within the Commission conduct all
of the charactersiation studies; at the moment there are three WPs
working on over 20 different projects:
Working Party IV.2.1 "Structure
and Properties of Commercial Plastics" (Working Party Chairman
and Titular Member of the Commission is Dr H M Laun).
Project topics include:
- Structure-property relationships of discontinuous fibre composites
- Rubber toughening of plastics
- Influence of reprocessing on structure-property characteristics
of pPVC
- Rheological and mechanical properties of P(MSAN/PMMA blends
in miscible and phase separated regimes of various morphologies
- Property improvement via interfacial chemical reaction-reactive
extrusion of EVOH/SMA and polyamide/MA-grafted polypropylene
- Structure and properties of hydrogenated NBR
- Effects of side chain branching on the processability of commercial
polycarbonates for blow moulding
- Studies on the biodegradable fibres made of poly(-caprolactone)
In addition, there are many feasibility studies under
way including topics such as:
-
Toughness characterisation of polymers using fracture
mechanics concepts
-
Structure and properties of polymeric foams
-
Understanding scratch resistance in commercial polymers
Working Party IV.2.2 "Molecular
Characterisation of Commercial Plastics" (Working Party Chairman
and Titular Member of the Commission is Dr D Berek).
Project topics include:
- Molecular characterization of polyamides 6, 11 and 12
- Nomenclature of chromatography of polymers and related substances
(Collaboration with Macromolecular Nomenclature (IV. 1) and the
Commission on separation methods in Analytical Chemistry (V.3)).
- Equipment experiences and exchanges through a project on size
exclusion chromatography dispersion correction
- Size exclusion chromatography and GPC methods applied to obtaining
molar mass averages on polystyrene
- Characterisation of polyelectrolytes in aqueous solution by
GPC, light scattering, viscometry, ultracentrifuge and similar
methods
- Precise determination of molecular weight distributions of
polyolefins by high temperature size exclusion chromatography
and hyphenated techniques
Working Party IV.2.8 "Modelling
of Polymerisation Kinetics and Processes" (Working Party Chairman
and Titular Member of the Commission is Prof M Buback). The working
party has 38 members and one project on the critical evaluated database
of kinetic parameters for free radical polymerization. Recent activitivies
have focused on pulsed laser polymerization and to use these methods
to "benchmark' other methods. >View
recent publications
Project topics include:
- Propagation rate coefficients for free-radical copolymerizations
- Termination rate coefficients in free-radical polymerizations
- Critical evaluation of methods and results
- Termination rate coefficients in free-radical copolymerizations
- Critical evaluation of methods and results
- Chain - transfer rate coefficients in free-radical polymerizations
- Critical evaluation of methods and results
- Chain transfer to monomer, chain transfer to chain-transfer
agents
- Initiator decomposition rates
In all, there are about 180 scientists actively involved
with this Commission.
Formerly
known as the Commission on Polymer Characterization and Properties
(IV.2); the commission was
discontinued in December 2001.
The work of the Polymer Division is now organized as projects.
