Date Feb. 29, 1996The present invention relates to agents for the pulp and/or surface sizing of paper, which comprise aqueous, solventless dispersions of cationic polymers, and to a process for sizing paper by using said agent. The sizing agents according to the present invention which can be used both in pulp and surface sizing obtain as active substance copolymers of a) 30-70 mole-% of a monomer I with b) 70-30 mole-% of a monomer II, and optionally c) 0-20 mole-% of C8-C30 monoolefins, and d) 0-10 mole-% of further monomers copolymerizable with a), b), and optionally c), the sum of monomers a), b), c), and d) amounting to 100 mole-%.
