摘要：A process for making a thermoplastic molding composition comprising (i)forming a vertically falling stream of molten polymer, and (ii) bringing at least oneadditive in solid or liquid states, in solution, in the form of a dispersion or in suspensioninto contact with at least a part of the surface of said stream and to introduce theadditive in said stream to produce combined stream, and (iii) introducing the combinedstream into a pump to form a pre-mix and (iv) introducing the premix into a mixer to forma homogeneous polymer melt. The entraining stream is then introduced to a pump toform a pre-mix which is then introduced to a mixer to form a homogeneous polymermelt. The process results in a compositions having advantageous material properties.
