    摘要: A process for polymerization of olefin monomers by forming a fluid stream containing catalyst, continuously feeding the fluid stream into an elongated polymerization reactor having at least two successive chambers separated by dividing plates having a diameter slightly smaller than that of the polymerization rector, feeding monomers, and an optional catalyst and donor into the polymerization reactor under temperature conditions to polymerize the olefin while maintaining a mixed flow in the chambers to polymerize the monomers and optional comonomer in the fluid, and removing the resultant polymer slurry from the polymerization reactor.

    摘要: The invention relates to a filter for brewed beverages, especially a coffee filter, and a process for producing such a filter, in which a fibrous material has pores with an average pore width (d) of at least about 0.1 mm measured at a fiber density of about 50% of the original fiber density of the material. The average pore width (d) is preferably in a range from 0.1 mm to 0.7 mm approximately and more preferably in a range from 0.1 mm to 0.4 mm approximately. The material is preferably paper. The pores are also preferably made by piercing with needles or by subjecting the fibrous material to water jets, providing an irregular pore edge.
