    Abstract: The invention relates to a method for producing a polymer dispersion by copolymerisation of 20 - 70 weight parts of a monomer mixture comprising c) 2.5 - 100 wt. % of one or more (meth) acrylic acid esters of monovalent, saturated C3-C8 alcohols as monomers A, and 0 - 97.5 wt. % of one or more other ethylenlically unsaturated monomers as monomers B in 100 weight parts of an aqueous solution which contains 5 - 35 wt.- % of a starch or a starch derivative, in emulsion polymerisation in the presence of an initiator containing peroxide groups, whereby the initiator and monomer can be continually dosed. In a first supply period of 5 - 60 minutes a first amount of an initiator is dosed and in a second supply period of 15 - 180 minutes a second amount of an initiator is dosed. The first amount of initiator is greater than the second amount of initiator.

    Abstract: A polymer dispersion is prepared by copolymerization of from 20 to 70 parts by weight of a monomer mixture comprisinga) from 2.5 to 100% by weight of one or more (meth)acrylates of monohydric, saturated C3-C8-alcohols as monomers A andb) from 0 to 97.5% by weight of one or more further ethylenically unsaturated monomers as monomers Bin 100 parts by weight of an aqueous solution which contains from 5 to 35% by weight of a starch or of a starch derivative by emulsion polymerization in the presence of an initiator containing peroxide groups, by a process in which the initiator and monomers are metered in continuously and wherein, a first amount of initiator is metered in over a first feed period of from 5 to 60 minutes and a second amount of initiator is metered in over a second feed period of from 15 to 180 minutes, the first amount of initiator being greater than the second amount of initiator.
