摘要:
During the manufacture of a master batch for a polyolefin resin film, organic polymer fine particles which contain a polyfunctional monomer (cross-linking agent) having at least one kind of two or more functional groups in a monomer unit constituting a polymer and is mixed with a polyolefin resin using an extruder are blended as an anti-blocking agent, thereby preventing the generation of die build-up around the outlet of the extruder.
