The Marcus series of polyethylene homopolymers are fully compatible with polyolefin polymers. Addition levels greater than 5% are not recommended as the mechanical properties of the polymer are impaired. Also, the end application characteristics such as sealability of film is diminished. In general, the polyethylene waxes act to decrease the “viscosity” of the polymer, that is, increase the melt index. This has the effect of improving the flow characteristics. Also, a fall in the power requirement occurs in converting operations. The MARCUS polyethylenes being of a highly crystalline nature have no tendency to migrate. In principal, these polyethylenes do significantly improve the processability of polyolefins and the potential exists to boost output. However, there is no influence upon reducing the melt fracture tendency of narrow molecular weight distribution polymer once the critical sheer rate is exceeded.
