pressure in the reactor is raised to 0 6 mpa n the meantime the pressure and temperature in the reactor are maintained constant after the reaction proceeds for 1 hr resin particles generated suspend in the solvent thereby forming polymer slurry in the solvent finally after the solvent is removed from the polymer slurry the ultra high molecular weight polyethylene resin required is obtained the properties of the ultra high molecular weight polyethylene resin obtained are as shown in table i in inert atmosphere 1 g magnesium chloride is dispersed in n hexane n butanol is added for reaction at 70 u00b0 c thereby forming magnesium chloride alcohol adduct solution or dispersoid subsequently aluminum diethyl monochloride is added to react with the magnesium chloride alcohol adduct forming an intermediate product the intermediate product is treated with ultrasound in an ultrasonic device titanium tetrachloride is added for a ti loading reaction afterwards said ti loading reaction mixture is treated with ultrasound in the ultrasonic device finally solid particles are recycled and the ultra high molecular weight polyethylene catalyst is obtained after nitrogen purging in a polymerization reactor solvent is added therein and stirring is started then 4 ml co catalyst triethyl aluminum and 1 5 mg said main catalyst are added in sequence the stirring speed is 210 rpm and the polymerization temperature is raised to 60 u00b0 c vinyl monomer is injected into the reactor the pressure in the reactor is raised to 0 6 mpa in the meantime the pressure and temperature in the reactor are maintained constant after the reaction proceeds for 2 hr resin particles generated suspend in the solvent thereby forming polymer slurry in the solvent finally after the solvent is removed from the polymer slurry the ultra high molecular.
