Abstract: PROBLEM TO BE SOLVED: To provide a popcorn polymer as a filter aid and/or a stabilizer for manufacturing beverage. SOLUTION: The insoluble, only slightly swellable popcorn polymer comprises (a) 0.1-99 wt.% of an N-vinyllactam or an N-vinylamine, (b) 0-10 wt.% of a bifunctional crosslinking agent component, and (c) 0.1-50 wt.% of at least one further monomer polymerizable by free radicals, provided that the weight percentages of the individual components are based on the total amount of the popcorn polymer and total up to 100%.
