    摘要: A process for preparing crosslinked polymer particles at high solids levels (i.e., > 40 wt%). Also provided is a method for predicting whether a selection of reaction conditions for preparing crosslinked polymer particles will exhibit a potential for forming a gel and a method for predicting whether a selection of reaction conditions will or will not result in the formation of a gel.
