POLYETHYLENE COMPOSITION FOR STRETCHED TAPE PRODUCTS

摘要

A polyethylene composition, in particular suitable for the preparation of monofilaments, mono-tapes and stretched tapes, is described. The polyethylene composition of the invention comprises 95.1%-99.5% by weight of polyethylene having a density above 0.930 g/cm<SUP>3</SUP> and a polydispersity M<SUB>w</SUB>/M<SUB>n</SUB> from 2.0 to 5.9, and 4.9%-0.5% by weight of polybutene. The bubble stability and the me- chanical properties of the films prepared from this composition are advantageously improved. The use of a polyethylene composition comprising 90.0%-99.5% by weight of polyethylene having a density above 0.930 g/cm<SUP>3</SUP>, and 10.0%-0.5% by weight of polybutene, for preparing monofila- ments, monotapes or stretched tapes is also described.
