Abstract:
Chapter 1 is a general and historical introduction to paint manufacture. Mention is made of a number of the polymerization methods used in paint manufacture and of the various uses to which different formulations of paint are used. Autoxidation and the factors controlling free radical reactions are also discussed. The overall aim of the thesis, the examination of the mechanism of autoxidation of allyloxy substrates is stated. In Chapter 2 examination of the radicals formed from the reaction of a number of monomeric model compounds with three different types of initiating radicals is discussed. By comparison with literature rate constants the position and type of radical attack is discussed. Thermal initiation of the radicals formed from the monomeric compounds is also examined. Chapter 3 examines the reaction of a number of polymers used in the preparation of a water-borne paint. The hardening process during the drying of a paint, both on the surface and sub-surface are also examined. From the results obtained in Chapter 2 the site of attack in the water-borne paint and related polymers is discussed. Chapter 4 examines the attempts to synthesise both an unsaturated bromoallyloxyether and an isotopically labelled alcohol or allyloxyether in order to further investigate the radicals which were detected by esr spectroscopy and spin trapping in Chapter 2 and 3.
