ABSTRACT:
A process for the preparation of aqueous polymer dispersions comprising polymerizing compounds with unsaturated ethylenic bonds at a temperature of 10.degree. to 100.degree. C. in the presence of an at least partially water-soluble free-radical initiator and at least one water-soluble protein and optionally present conventional adjuvants with the starting mixture containing not more than 40% of the total monomers and the remaining monomer being added by metering during the polymerization, the initiators being at least one member of the group consisting of ketone peroxides and organic hydroperoxides in an amount of at least 30 mmol per kg of total monomer mixture and optionally present water-soluble reducing agents and the amount of protein being at least 3% by weight based on the total monomer weight and at least 30% by weight is added during the polymerization and the isoelectric point of the protein is not reached or exceeded during polymerization.
