Abstract: The present invention is directed to a process for producing a modified olefin polymer having increased melt strength in an extruder. The process comprising the steps of: (A) contacting a stream comprising particles of an olefin polymer with a vapour stream of a functionally unsaturated compound in vapour phase thereby producing a first mixed stream; (B) passing the first mixed stream to an extruder; (C) melting the polymer particles of the first mixed stream in the extruder; (D) introducing a stream of a free radical generator either into the first mixed stream or into the extruder; and (E) extruding the first mixed stream and the free radical generator at a temperature which is greater than the decomposition temperature of the free radical generator and the melting temperature of the olefin polymer but less than the decomposition temperature of the olefin polymer thereby producing the modified olefin polymer in the extruder.

Abstract: The invention relates to solid particles and to a method for the production thereof from a flowable starting material and a solid part, wherein the flowable starting material is split into droplets which are introduced along a trajectory into a solidification liquid in which they are solidified in the form of the solid particles. The invention is characterized by the use of solidification liquid and, if the flowable starting material contains actinide oxide, the solidification liquid steadily flows, thereby making it possible to produce solid particles having a greater sphericity and a narrow particle sized distribution.
