The invention relates to the field of macromolecular polymers, and discloses an alpha-olefin-maleic anhydride copolymer and a preparation method and application thereof. The copolymer comprises a structural unit represented by formula (1) and a structural unit represented by formula (2); Wherein, R is an alkane having 6-12 carbon atoms; based on the total molar amount of the copolymer, the molar content of the structural unit shown in the formula (1) is 48-53%, and the molar content of the structural unit shown in the formula (2) is 48-53%. The molar content is 47‑52%. The copolymer is in the form of microspheres, and the surface of the copolymer microspheres is clean and pollution-free, and the particles of the microspheres are uniform. It can be used as a filling modifier in polyolefins, especially polypropylene, without causing a significant decrease in polymer properties. . |
