The system catalu00cdtico type metaloceno supported, process of synthesis and use of the same, high density polyethylene and linear polyethylene of low or ultra low density

摘要

The system catalu00cdtico type metaloceno supported, s1ntese process and use of the same, high density polyethylene and linear polyethylene of low or ultra low density.The present invention relates to a catalytic system composed of metaloceno in a silica magnesia support hybrid synthesized by sol gel method, the preparation process of the catalytic system based on metaloceno supported from a silica magnesia synthesized hybrid PE This method sol gel.And the polymers and copolymers of ethylene with high content of incorporation of the olefin prepared with the use of higher catalytic system.
