Notes:
The use of stabilizer systems containing phosphites in polyolefins is well-established in the technical and patent literature. In addition to the known effects of improved heat and color stability for polyolfins, we have recently found that phosphite-containing stabilizer systems impart a process stabilizing effect as evidenced by melt flow analysis. By monitoring the poly-olefin melt flow after multiple extrusions with increasing temperature, it was found that the combination of phenolics and phosphites has a marked influence on the control of melt flow of polyolefins and the effect appears to be synergistic in operation.
