ABSTRACT OF THE DISCLOSURE: 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 poly- merization 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, dicyclo- pentadiene, 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).
