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: | 1644-3624 1895-1066 |
