摘要：
The invention provides water-swellable polymer compositions having reduced dusting tendencies, i.e, reduced amounts of unassoiated dust having a maximum diameter less than or equal to 10 microns and/or the tendency to generate reduced amounts of unassociatcd dust having a maximum diameter less than or equal to 10 microns upon attrition, and a process for preparing such compositions.
