| Abstract: | Rosin modified nonylphenolic resin was synthesized from rosin, maleic anhydride, nonylphenolic and solid formaldehyde, pentaerythritol as raw materials in the presence of magnesium oxide and zine oxide by one-step method. The optimum composition of rosin modified nonylphenolic resin was determined as follows： the contents of maleic anhydride and nonylphenolic, formaldehyde were 3 % and 35 % respectively. The molar ratio of nonylphenolie to formaldehyde and rosin to pentaerythritol were 1 ： 2 and 1 ： 0.98 respectively. The effects of maleic anhydride amount, nonylphenolic and formaldehyde amount and polyol kinds on the properties such as viscosity, solubility and softening point were examined. |
