HIGH DENSITY ETHYLENE HOMOPOLYMERS AND BLEND COMPOSITIONS

摘要

This invention relates to novel homopolymers important for applications wher e a high density is needed to ensure certain mechanical properties like abrasi on resistance, indentation resistance, pressure resistance, topload resistance, modulus of elasticity, or morphology (for the chlorination of PE to CPE) and additional advantages such as melt processability. This invention also relat es to blend compositions containing the novel homopolymer, the use of which allows the incorporation of more comonomer in the additional components of t he blend (for the same overall density) resulting in increased tie molecule formation and improvement in properties such as ESCR, toughness and impact strength. The blend can be obtained by dry or melt mixing the already produc ed components, or through in-situ production by in parallel and/or in series arranged reactors. These resins can be used in applications such as films, blow molded, injection molded, and rotomolded articles, fibres, and cable an d wire coatings and jacketings and, various forms of pipe.
