Title:
POLYOLEFIN RESIN COMPOSITION AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2016/074243
Kind Code:
A1
Abstract:
Provided are a polyolefin resin and a preparation method therefor. The preparation method for the polyolefin resin comprises olefin monomers undergoing a polymerisation reaction in the presence of an olefin polymerisation catalyst component and a cocatalyst, the olefin polymerisation component containing halloysite, a transition metal component, a non-transition metal component and the cocatalyst. When the transition metal component is a titanium tetrahalide and/or a titanium alkoxide, the non-transition metal component is a magnesium-containing compound. When the transition metal component is a metallocene compound and/or a non-metallocene compound, the non-transition metal component is an aluminium-containing compound. When the transition metal component is mixture of a titanium tetrahalide and/or a titanium alkoxide and a metallocene compound and/or a non-metallocene compound, the non-transition metal component is a mixture of a magnesium-containing compound and an aluminium-containing compound. The polyolefin composition prepared via the present method has a relatively high melt strength and relatively high mechanical properties.
