The effect of the chainlength of the alkylsubstituent in alkylphenols (3—9 C-atoms) on the course of synthesis and characteristics of resins prepared on their basis as well as on the dryingtime, mechanical properties and chemical resistance of lacquer coatings containing these resins has been investigated. It has been found that the longer is the alkil substituent chainlength, the longer is both the curing time of resins and the time of their fusing together with tung oil till the attainment of a defined viscosity of the molten mass, as well as the dryling time of lacquer coatings. The length of the alkil substituent has, however, no effect on the chemical resistance of coatings and on their mechanical properties (excluding hardness). The best results are obtained in general when using 100-percent butylphenol with a high content of para izomer in the synthesis of phenolic resins.
