摘要:
A high solids, pumpable stable dispersion of substantially anhydrous water soluble or swellable polymer particles contains at least 70% by weight polymer and contains 1 part by weight fine polymer particles below 10 microns in size and 0.1 to 7 parts by weight coarse polymer particles having a size of 10 to 300 microns with substantially no particles above 300 microns.
