▎ 摘 要
NOVELTY - A polymethyl acrylate/grapheme nano composite polymer pour point depressant is prepared by ultrasonically dispersing oxidized graphene in organic solvent, obtaining suspension, adding polymethacrylate and initiator, polymerizing under inert atmosphere at 70-90 degrees C, obtaining dope, adding reducing agent, reacting, and carrying out post-treatment method. USE - Method for preparing polymethyl acrylate/grapheme nano composite polymer pour point depressant (claimed). ADVANTAGE - The method is simple and easy. The product is stable, has excellent depressive effect. It is suitable for 0# diesel.
