POLYMER FINE PARTICLES CAPABLE OF PREVENTING THE GENERATION OF GUM IN EXTRUSION MOLDING

摘要

In order to prevent the generation of gum in the outlet of an extruder in producing a masterbatch for polyolefin resin film, fine particles of an organic polymer, which are to be incorporated with a polyolefin resin using an extruder, are added as an antiblocking agent to the polyolefin resin, said organic polymer including at least one kind of at least bifunctional monomer (crosslinking agent) among the constituent monomer units.
