Abstract

A series of film formers based on aldehyde oils, derived by reductive ozonolysis of soybean and linseed oils was prepared by a two-step reaction with a resinous polyol, styrene-allyl alcohol copolymer. The methyl acetals of the di- and monoaldehyde oils were interchanged with the hydroxyl functionality of the resinous polyol with potassium acid sulfate as the catalyst as follows: (a) The heterogeneous mixture was heated only to clarity in the first step. This consumed about 20–25% of the hydroxyl groups of the resinous polyol. (b) Films of the partially reacted products of (a) were cast and cured at various temperatures between 100 and 175 C for variable periods of time. The films showed good hardness, scratch and chemical resistance. Some yellowing was observed. The film former in the (a) stage was compatible with melamine and urea-formaldehyde resins and, upon baking, these compositions also produced clear, hard chemical-resistant films.
