The Polymer Division of the Royal Australian Chemical Institute in association with the Australian Academy of Technological Sciences and Engineering has established a prestigious lecture series to promote polymer science and engineering in Australia which are known as the Solomon Lectures, in honour of Prof. David Solomon. These lectures are given by an eminent polymer scientist, and are held at various locations throughout Australasia

Professor Krzysztof Matyjaszewski, Carnegie Mellon University, Pittsburgh, USA  

Title:

Atom Transfer Radical Polymerization‐ from Mechanism and Synthesis to Materials and Applications

Date:

Tuesday 23 October, 2012

Time:

11:00am 

Venue:

AIBN Seminar Room - Level 1

 

 

ABSTRACT:

Copper‐based ATRP (atom transfer radical polymerization) catalytic systems with polydentate nitrogenbased ligands is among most efficient controlled/living radical polymerization systems. Recently, by mechanistic understanding of ATRP, new initiating/catalytic systems were developed with Cu level reduced to a few ppm. Various reducing agents, including metals, organometallic species, sugars, amines, phenols, monomers ligands, radical initiators or electrical current and light have been successfully applied.

ATRP of acrylates, methacrylates, styrenes, acrylamides, acrylonitrile and other vinyl monomers provides polymers in a large range of molecular weights and with low dispersities. Polymers can be formed quantitatively in bulk, in solution and in dispersed media. Water can serve both as solvent for many water soluble polymers and also as medium for microemulsion, miniemulsion, dispersion and suspension polymerization. Block, graft, star, hyperbranched, gradient and periodic copolymers, molecular brushes and various hybrid materials as well as bioconjugates have been prepared. Many advanced nanostructured functional materials were designed and prepared by ATRP via a precise design, synthesis, processing and characterization of targeted materials for specific applications. The (co)polymers made by ATRP find applications as components of advanced materials such as coatings, elastomers, adhesives, surfactants, dispersants, lubricants, additives, but also as specialty materials in biomedical and electronic areas and could affect the market of ~$20 billion/year.
