Title:
METHOD FOR PRODUCING POLYVINYLIDENE FLUORIDE-BASED POLYMER PARTICLES OF UNIFORM PARTICLE SIZE
Document Type and Number:
WIPO Patent Application WO/2024/005304
Kind Code:
A1
Abstract:
The present invention relates to a method for producing polyvinylidene fluoride-based polymer particles of a uniform particle size, and specifically, to a method for producing polyvinylidene fluoride-based polymer particles of a uniform particle size, the method comprising the steps of: obtaining a mixture containing vinylidene fluoride (VDF), a dispersion medium, and a polymerization initiator; stirring the mixture at a first stirring speed of 350 rpm to 800 rpm and raising the temperature to a first temperature; and stirring the mixture at a second stirring speed equal to or less than the first stirring speed and equal to or greater than 200 rpm and raising the temperature from the first temperature to a second temperature.
