Abstract:
A process for producing a polyolefin-based resin composition, which comprises melt-kneading 100 parts by weight of a polyolefin-based resin and not less than 0.05 parts by weight and less than 2 parts by weight of polymer fine particles containing 0.10 to 90% by weight of a volatile component based on the weight of the polymer fine particles and the volatile component, as an anti-blocking agent;wherein said polymer fine particles are made of polymer obtained by polymerizing at least one monomer selected from the group consisting of styrene, methyl acrylate, methyl methacrylate, 2-ethylhexyl acrylate and 2-ethylhexyl methacrylate, and wherein said volatile component is selected from the group consisting of saturated hydrocarbons, ketones, aldehydes, ethers, mixtures thereof, water and mixtures of water and alcohol.
