| Abstract: | The high hardness environmental friendly polyester wax was synthesized by direct melt polycondensation with dodecanedioic acid and glycol as the main raw materials.The structure of the wax was characterized by IR.The effects of the ratio of reactants,reaction temperature,reaction time and catalyst types on the product were investigated.The suitable reaction conditions are:n(glycol)∶n(dodecanedioic acid)=1.5∶1,reaction temperature is 160℃,reaction time is 6 h,p-toluenesulfonic acid is used as catalyst.Under above conditions,the dropping point is 98℃,the acid value is 6.25 mg KOH/g,the penetration degree is 1.6(0.1mm)and the viscosity is 133.14 mm^2/s. |
