| Abstract: | Methylcyclohexanone-formaldehyde resin was synthesized from methylcyclohexanone and formaldehyde by polycondensation reaction in the presence of NaOH as catalyst. Effects of synthesis conditions on the softening point and hydroxide value of the resin were studied. The optimal conditions were found as follows: molar ratio of formaldehyde to methylcyclohexanone 1. 4, 0. 4% NaOH relative to methylcyclohexanone, reaction temperature 130℃and reaction time 6 h. Softening point of the resin was 110. 2℃, and the hydroxide value(KOH) was 32. 8 mg/g, The resin has good solubility in common solvents in coating. |
