| titleOfInvention | Method for producing stable spherical particles having a target particle size by controlling the cooling rate |
| abstract | The present invention relates to a method for obtaining stable particles by spheroidization having a desired size by controlling the cooling rate, and more specifically, to prepare polymer particles having a weight average molecular weight in the range of 10,000 to 150,000 g / mol through free radical polymerization. step; Dispersing the polymer particles in a poor solvent and then heating and dissolving the polymer particles to obtain a polymer solution; Cooling the polymer solution to prepare polymer spherical particles; And it relates to a method for producing a stable spherical particles comprising the step of washing and drying the polymer spherical particles to powder. When using the method for producing a stable polymeric spherical particles according to the present invention, unlike the conventional method, by heating and melting the polymer particles dispersed in the poor solvent and re-precipitating only by controlling the cooling rate, spherical particles having a desired size can be easily obtained. In addition, when a spherical particle having a different size is desired, polymer particles having a desired size can be easily obtained by repeating only re-dissolution and re-precipitation without complicated processing processes as in the conventional method, and thus, there is an advantage of easily recycling the resin. |
