Radical Orbital Switching

About

Overview A new technique pioneered at ANU has potential to extend free radical polymerisation to reactions requiring temperatures and conditions in which existing techniques cannot be used, and to enable new methods of control in polymerisation. Background Free radical polymerisation is one of the most versatile forms of polymerisation available, due to the relatively non-specific nature of free radical chemical interactions. Its many applications include processes for manufacturing polystyrene, thermoplastic block copolymer elastomers (used in adhesives, toys and footwear), chemical surfactants, cardiovascular stents and lubricants. In 2001, approximately 36 per cent of polymers produced in the US were made using free radical polymerisation. Opportunity A new technique pioneered at ANU has potential to extend free radical polymerisation to reactions requiring temperatures and conditions in which existing techniques cannot be used, and to enable new methods of control in polymerisation. This technology results in: increased scope of free radical polymerisation reduced costs of manufacture due to lower reaction temperatures potential for control of polymerisation no need for metal catalysts or volatile compounds.
