  • Manufacture of shear-resistant aqueous copolymer emulsions
    Patent number: 4051093
    Abstract: Shear-resistant aqueous copolymer emulsions which can be used for sizing paper are manufactured by first copolymerizing, in the aqueous phase of an aqueous emulsion, using conventional polymerization initiators which form free radicals, (A) from 0.5 to 15 per cent by weight of monomers containing a polymerizable C.dbd.C bond and at least one carboxyl and/or sulfonic acid or phosphate or phosphite group with (B) from 5 to 30 per cent by weight of monomers containing a C.dbd.C bond and a tertiary or quaternary amino group, or a nitrogen-containing heterocyclic group, and then adding, while continuing the copolymerization, (C) from 0 to 94.5 per cent by weight of styrene and/or acrylonitrile and (D) from 0 to 94.
