| titleOfInvention | A kind of acid-modified C9 petroleum resin and its molecular weight controllable preparation method |
| abstract | The invention belongs to the technical field of petroleum resins and polymer materials. The acid-modified C9 petroleum resin provided by the invention is obtained by graft-modifying the basic C9 petroleum resin obtained by polymerization, and its softening point is controlled at 100-180° C. The z-average z-average molecular weight is controlled at 6000-15000; the molecular weight controllable preparation method firstly uses the refined C9 refined from the C9 fraction of ethylene cracking as the polymerization raw material, and uses cationic catalytic polymerization under normal temperature conditions to obtain the basic C9 petroleum resin; Then, the base C9 petroleum resin obtained above is subjected to graft modification with maleic anhydride under heating and melting conditions to obtain acid-modified petroleum resin. The invention regulates the molecular weight of the basic C9 resin by adjusting the composition of the reaction materials and the content of each material component, and then through the grafting technology, so that the molecular weight of the acid-modified petroleum resin can finally be controlled, and the control range is wide. . |
