Composition and process for forming a rotating process for production of a composition of micropelotas for rotational molding, the use of a composition of micropelotas,Article polymeric molded alternately and apparatus for the production of pellets of polyolefin molding press.The invention provides a production process of a composition of micropelotas in rotational molding.Said process comprising: producing a mixture of a polyolefin and, optionally, at least one additive; extruding the mixture to form a fused through holes in a matrix; pelotizar miStura extruded through these holes to form micropelotas having a D (V, 05) of particle size distribution of 0.1 to 1 mm, and a value of the relationship of D (V, 0.9) - D (V, 1) to D (V,05) of not more than 1; drying the said micropelotas until a residual water content of not more than 1% by weight; and, when desired, storing the said micropelotas.
