Embodiment 1
[0047] Embodiment 1, the ethylene cracking C that will contain diolefins, monoolefins 5 The distillate was subjected to Diels-Alder reaction at a temperature of 140°C and a pressure of 12.0 MPa for 9 hours, then cooled and discharged, and rectified to remove unreacted C 5 component, obtained as C 10 、C 15 、C 20 Be the mixing component of main component (the weight percentage of each composition in this mixing component is: C 10 75-99%, C 15 1~15%, C 20 0 to 3%, C5 fraction 0 to 1%); then dry the mixed components until the water content is 100ppm, add them into the reactor, heat to 90°C under stirring, and then add 0.5% of the weight of the mixed components without Aluminum trichloride in water, polymerized for 24 hours at a temperature of 190°C and a pressure of 5 MPa to obtain a crude resin; add mineral oil to dilute the crude resin, wash with water, settle to obtain a crude resin solution, and distill the crude resin solution under reduced pressure to obtain a resin pro...
Embodiment 2
[0048] Embodiment 2, the ethylene cracking C that will contain diolefins, monoolefins 5 The distillate was subjected to Diels-Alder reaction at a temperature of 220°C and a pressure of 6.0 MPa for 12 hours, then cooled and discharged, and rectified to remove unreacted C 5 component, obtained as C 10 、C 15 、C 20 Be the mixing component of main component (the weight percentage of each composition in this mixing component is: C 10 75-99%, C 15 1~15%, C 20 0~3%, C 5 Fraction 0-1%); then the mixed component is dried to a water content of 15ppm, added to the reactor, heated to 60°C under stirring, and then added with anhydrous aluminum trichloride of 2.5% by weight of the mixed component, Polymerize at a temperature of 150°C and a pressure of 3 MPa for 10 hours to obtain a crude resin; add naphtha to dilute the crude resin, wash and settle to obtain a crude resin solution, and distill the crude resin solution under reduced pressure to obtain a resin product. After measurement...
Embodiment 3
[0049] Embodiment 3, the ethylene cracking C that will contain diolefins, monoolefins 5 The distillate was subjected to Diels-Alder reaction at a temperature of 300°C and a pressure of 1.0 MPa for 3 hours, then cooled and discharged, and rectified to remove unreacted C 5 component, obtained as C 10 、C 15 、C 20 Be the mixed component of main component (the weight percentage of each composition in this mixed component is: C 10 75-99%, C 15 1~15%, C 20 0~3%, C 5 Fraction 0-1%); then dry the mixed components until the water content is 200ppm, add to the reactor, heat to 75°C under stirring, then add anhydrous aluminum trichloride with 1.0% weight of the mixed components, Polymerize at a temperature of 100°C and a pressure of 0 MPa for 35 hours to obtain a crude resin; add n-pentane to dilute the crude resin, wash with water, and settle to obtain a crude resin solution, and distill the crude resin solution under reduced pressure to obtain a resin product. After measurement, ...
