Abstract: Synthetic method of high-active catalyst for ALPA-olefin polymerization by binding titanium compound such as TiCl4 on magnesium compound carrier is disclosed in this invention. Alcohol is added to mixture of magnesium compound and surfactant whose mixing ratio by weight is 1.0:0.1 to 1.0:0.3 to form magnesium-surfactant-alcohol complex, then 0.1 to 0.5 mole parts of electron donor such as aromatic carboxylic acid ester for magnesium compound is added to form magnesium-surfactant-electron donor-alcohol complex. Lastly, above-mentioned complex solution is dispersed using atomizer for crystallization to produce high-active catalyst for ALPA-olefin polymerization.

Abstract: The method comprises the steps of; (i) introducing a mixture of purified monomer, initiator and pare-forming agent into a 4-necked reactor with a suspension stabiliser and aq. solution and suspending the mixture to provide homogeneous organic droplets at a temperature below the decomposition temperature of the initiator; (ii) heating the suspension gradually to a polymerization temperature and maintaining the polymerization temperature to react the monomer completely by suspension polymerization; (iii) separating the beads produced; (iv) washing the beads with water, acetone and tetrahydrofuran(THF) successively; (v) drying the beads; (vi) adding the bead to a solution of monomer and thinner to fill the pores of the bead with diluted monomer; (vii) introducing further suspension stabilised and aqs. solution; (viii) carrying out suspension polymerization again to coat a lightly crosslinked gel polymer on the surface of pores in the porous polymer bead; (ix) washing and drying the beads. The polymer beads are used as support for some components of a reactive system, e.g. reagent or catalyst.
