| titleOfInvention | Method for producing porous polyolefin particles |
| abstract | The present invention relates to a method for producing porous polyolefin particles,n n n 1) dissolving at least one crystalline polyolefin in a solvent to form a solution consisting of 0.1-50 wt.% Of the polyolefin, wherein the formed initial polyolefin solution contains between 5 ppm and 20 wt.% Of the nucleating agent;n n n 2) a polyphase system is formed by dispersing the resulting polyolefin solution in a non-solvent at a temperature higher than the crystallization temperature of the polyolefin in the polyolefin solution;n n n 3) with stirring, the polyphase system is cooled below the crystallization temperature of the polyolefin in the polyolefin solution at a rate between 0.05 and 10 ° C./min to form polyolefin-containing particles;n n n 4) separating the polyolefin-containing particles from the liquid;n n n 5) drying the polyolefin-containing particles at a temperature below the crystallization temperature of the polyolefin in the initial polyolefin solution. |
