Process for the preparation of protective colloid-stabilized, emulsifier-free, aqueous dispersions

   
   

Process for the preparation of protective colloid-stabilized, emulsifier-free, aqueous dispersions based on at least two monomers selected from vinylaromatics, 1,3-dienes and/or (meth)acrylates, in the presence of assistants and, if required, further comonomers in an amount of from 0.1% by weight to 20% by weight, based on the total amount of monomers, wherein at least 10% by weight of the total amount of water are added to the reaction vessel only after the monomers have been added to the reaction vessel and the conversion is at least 40%, based on 100% of the monomers.

Processo para a preparação das dispersões colóide-estabilizadas, emulsifier-livres, aqueous protetoras baseadas ao menos em dois monomers selecionados do vinylaromatics, 1,3-dienes e/ou (os meth)acrylates, na presença dos assistentes e, se requerido, de uns comonomers mais adicionais em uma quantidade de 0.1% pelo peso a 20% pelo peso, baseada na quantidade total de monomers, wherein ao menos 10% pelo peso da quantidade total de água estão adicionados à embarcação da reação somente depois que os monomers estiveram adicionados à embarcação da reação e a conversão é ao menos 40%, basearam em 100% dos monomers.
