ABSTRACT:
Biologically degradable aqueous dispersions of vinyl ester polymers are provided which have a solids content of 20 to 70% by weight, based on the total weight of the dispersions, and have been prepared by free radical polymerization by the emulsion polymerization process, wherein, in the presence of
10 to 50% by weight, based on the monomer phase, of biologically degradable plasticizer and 0.5 to 15.0% by weight, based on the monomer phase, of biologically degradable emulsifier and/or biologically degradable protective colloid,
a monomer phase comprising
