Stable, gel-free, water-in-oil microdispersions comprising a continuous phase of an oil and an emulsifier and a discontinuous phase of an aqueous solution of a hydroxamated vinyl polymer are disclosed. Also disclosed is a method for the production of the above-described microdispersions wherein neutralized hydroxylamide and excess base are reacted with a microdispersion of the vinyl polymer.

Los microdispersions estables, gel-libres, del agua-en-aceite que abarcaban una fase continua de un aceite y de un emulsor y una fase discontinua de una solución acuosa de a hydroxamated el polímero del vinilo se divulgan. También se divulga un método para la producción de los microdispersions descritos antes en donde la base neutralizada del hydroxylamide y del exceso se reacciona con un microdispersion del polímero del vinilo.
