Molecular weight picture varnish

Low molecular weight cyclohexanone resins have been used as picture varnishes since the 1950s. Their synthesis from cyclohexanone and methyl cyclohexanone in the presence of... 

The natural resins used for picture varnishes are made up of mixtures of larger molecules, many of which have now been separated and identified. The molecular formula of the major component of dammar, oleanonic acid (Boon and van der Doelen, 1999), is C30H45O3, MW 454. There are many terms that are used for this concept (Table 2.2), but this book will use molecular weight for simplicity.
