Dilution polymerization of linseed oil

Summary An inert diluent, molecularly distilled mineral oil, when present in 90% concentration, permitted, in linseed oil, the polymerization of acyl groups in the absence of inter-glyceride reaction. Comparison of the data for the polymerization of linseed oil in 10, 20, and 100% concentrations showed a marked concentration dependence for the following: polymerization of acyl groups and glyceride molecules; change in specific refraction and the ratio of percentages by weight polymeric acyl groups to polymeric glyceride molecules.
