Abstract
Micronized polymers suitable for use in fuels and lubricants having a particle size distribution of less than 30 microns obtained from water-soluble solid organic polymers is provided. A water-soluble solid organic polymer having a number average molecular weight in the range of 1000 to 200,000 is subjected to a molecular segmentation in a polar solvent in a polymer to solvent ratio in the range of 1:1 to 1:10 to produce a micronized polymer having a particle size distribution of less than 30 microns.
