Embodiment 1
[0050] (1) Preparation of organic polymer carrier
[0051] In a 2-liter Erlenmeyer flask equipped with a stirrer, a reflux condenser and a thermometer, 60 grams of acrylonitrile-divinylbenzene copolymers (the content of divinylbenzene units are 10% by weight) The micropore capacity of 5000A micropores is 0.62ml / g, the radius is 35-50,000A micropores have a micropore capacity of 0.71ml / g, and the average particle size is 50μm). And add 206 grams of diethylenetriamine and 36 grams of distilled water, react at 130-140° C. for 4 hours, filter the supernatant, and wash the obtained solid twice with 1 liter of distilled water. Dry in vacuo to a flowable solid (158 g).
[0052] The obtained olefin polymerization catalyst support had a pore volume of 0.46 ml / g for pores with a pore radius of 100-5,000 Å, a pore volume of 0.48 ml / g for pores with a pore radius of 35-50,000 Å, and an average particle size of 45 μm.
