  • Method of producing pelletized polyolefin
    Publication number: 20050228118
    Abstract: Rotational moulded products are prepared by producing a mixture of a polyolefin and optionally at least one additive, extruding this mixture in melt form through orifices in a die, pelletizing the mixture extruded through the orifices to form micropellets having a particle size distribution D(v, 0.5) of 0.1 to 1 mm, and a value of the ratio of D(v, 0.9)-D(v, 0.1) to D(v, 0.5) of no more than 1, drying the micropellets to a residual water content of no more than 1% weight, and if desired packaging the micropellets.
    Type: Application
