| Abstract: | Rosin modified nonylphenolic resin was synthesized by one - step synthesis in laboratory. The effects including reaction medium pH value, molar ratio of nonyl phenol/methyl aldehyde, nonyl phenol, rate of adding methyl aldehyde, and condensation time on quality of the product were investigated. The optimum conditions of synthesis were determined as follows: molar ratio of nonyl phenol/methyl aldehyde 1:2.3, reaction medium pH value 9, ratio of para - /ortho - nonyl phenol more than 90:10, and condensation time 3.5 - 4 h. The quality of the product by one - step synthesis are up to or over that of the product prepared by two - step synthesis. |
