Abstract: Water-soluble homopolymers and copolymers of di-C1-C3-alkylaminoneopentyl (meth)acrylates, the homopolymers and copolymers having a K value of from 150 to 300, are used as retention agents, drainage agents and flocculants in papermaking. Increased retention, drainage rate and flocculation are achieved in comparison with the conventional basic polyacrylates.

Abstract: Production of polymers in bead form by forming a water-in-oil suspension of an aqueous solution containing at least one water-soluble ethylenically unsaturated monomer in an inert hydrophobic liquid organic dispersion medium and polymerizing the suspended monomer in the presence of a polymerization initiator and a protective colloid obtained by polymerizing (A) 60 to 100% by weight of at least one monomer selected from the group consisting of cyclopentadiene, dicyclopentadiene, tricyclopentadiene and alkyl-substituted derivatives thereof, and (B) 0 to 40% by weight, based on the mixture of (A) and (B), of a mono- or diethylenically unsaturated monomer copolymerizable with (A).
