|Title:||Preliminary observations on the copolymerisation of acceptor monomer: Donor monomer systems under microwave irradiation||Contributor(s):||Fellows, Christopher (author)||Publication Date:||2005||DOI:||10.2478/BF02476236||Handle Link:||https://hdl.handle.net/1959.11/1437||Abstract:||The mechanistic rationalisation of specific 'microwave effects' previously reported in a range of chemical reactions suggests that they may be observable in the free-radical copolymerisation of comonomer pairs capable of forming donor-acceptor complexes. Polymerisation under microwave irradiation is carried out for several comonomer pairs with weak donor-acceptor interactions, and no acceleration in rate or change in degree of alternation attributable to changes in propagation are observed. An increase in reaction rate of 150–200% is observed for all systems, with trends in molecular weight suggesting this was due to an increase in radical flux. This is consistent with earlier reports of rate enhancement for free-radical polymerisations using the initiator 2,2'-azobis-isobutyronitrile, and it is proposed that microwave irradiation may reduce the amount of geminate radical recombination.||Publication Type:||Journal Article||Source of Publication:||Central European Journal of Chemistry, 3(1), p. 40-52||Publisher:||Versita||Place of Publication:||Poland||ISSN:||1895-1066
