Abstract
Distribution of a fluid additive through multiple passages across the cross section of a pipe carrying molten/fluid polymer wherein the polymer flow is distributed across the cross section of the pipe provides uniform distribution of the fluid additive when the passages are directed in the downstream direction of flow and substantially parallel to the longitudinal axis of the pipe carrying the polymer. This device is advantageous for mixing of two or more fluids independent of the viscosity differences.
