ABSTRACT:
A process for the production of an emulsifier-free self-crosslinkable rubber latex (meth)acrylic acid, N-alkoxymethyl (meth)acrylamide and acyclic conjugated dienes arylvinyl monomers and/or (meth)acrylonitrile, wherein an aqueous emulsion is prepared by adding at least part of the (meth)acrylic acid, part of the diene and further monomers to water, the polymerization reaction is initiated by the addition of an aqueous solution of a peroxodisulphate and is carried out in a first stage at a pH-value of from 3.5 to 7 until at least 50% of the monomers have been polymerized, the rest of the monomers and initiator are added in one or more further stages and the polymerization reaction is continued at a pH-value of from 3.5 to 7 until at least 50% of the monomers and, in the last stage, until from 85 to 100% of the monomers have been polymerized.
