| titleOfInvention | Coated proppants and methods of making and use thereof |
| abstract | Methods for producing proppants with block copolymer proppant coating include coating proppant particles with the block copolymer proppant coating to produce coated proppants with block copolymer proppant coating. The block copolymer proppant coating is a block copolymer composition having at least one copolymer backbone. Each copolymer backbone comprises at least two hard segments and a soft segment disposed between the at least two hard segments. Additionally, a proppant comprising a proppant particle and a block copolymer proppant coating includes a block copolymer composition having at least one copolymer backbone, in which each copolymer backbone comprises at least two hard segments. A soft segment is disposed between the at least two hard segments. The copolymer backbone has at least one anhydride group grafted onto the soft segment. Furthermore, the anhydride group is crosslinked by an amine-containing crosslinker. |
