Glass transition temperatures of oxidative polymerized films were measured by the dynamic+mechanical method and by l i e w i d t h measurements (NMR). The correlation was studied in relation to the chemical structure. The films investigated were polymerized linseed oil, alkyd resins, phenolic varnis
## Abstract From a consideration of molecular dimensions and bond angles, it is deduced that a Novolak resin must consist of highly kinked, asymmetrical molecules. As a result, it is concluded that such a resin, when hardened with βhexa, β will contain much less than the theoretically possible numb
