The invention relates to crosslinkable PVB (polyvinyl butyral), a production method of the crosslinkable PVB, and a method utilizing the crosslinkable PVB to produce a crosslinkable PVB film, belongs to the technical field of polymer materials, and provides the crosslinkable PVB, the production method of the crosslinkable PVB, and the method utilizing the crosslinkable PVB to produce the crosslinkable PVB film. The crosslinkable PVB film can be prepared by crosslinkable PVB resin with smaller polymerizing degree; the viscosity of the melting body of the crosslinkable PVB is smaller, the fluidity during processing is better, the crosslinkable PVB resin can be mixed and plasticized with a plasticizing agent under the conditions of lower temperature and screw rod rotation speed, so the energy consumption is decreased, and the side effect caused by high temperature is reduced.
