Abstract

<B>"DISPERSãO à BASE DE áGUA E SEU PROCESSO DE PREPARAçãO"<D>A presente invenção trata de uma dispersão à base de água útil para formar composições de revestimento aquosas que contêm um material hidrofóbico disperso, um veículo aquoso e um dispersante de polímero ramificado (aglutinante); sendo que o polímero ramificado tem um peso molecular médio ponderal de aproximadamente 5.000 a 1000.000 e contém 20% a 80% em peso de uma cadeira principal hidrofílica e de modo correspondente 80% a 20% em peso de cadeias laterais de macromonómeros; sendo que a cadeia principal é de monómeros etilenicamente insaturados polimerizados e 2% a 30% em peso, com base no peso da cadeia principal, de monómeros etilenicamente insaturados polimerizados que têm um grupo com funcionalidade de ácido; e onde pelo menos 10% dos grupos com funcionalidade de ácido são neutralizados com uma amina ou uma base inorgânica e são hidrofílicos em comparação com as cadeias laterais; e as cadeias laterais são de macromonómeros de monómeros etilenicamente insaturados polimerizados que são polimerizados na cadeia principal através de um grupo etilenicamente insaturado e os macromonómeros possuem um peso molecular médio ponderal de aproximadamente 1.000 a 30.000 e onde o coeficiente em peso entre o material hidrofóbico e o aglutinante é de aproximadamente 1/100 a 200/100.<B> "WATER-BASED DISPERSION AND ITS PREPARATION PROCESS" <D> The present invention addresses a water-based dispersion useful for forming aqueous coating compositions containing a dispersed hydrophobic material, an aqueous vehicle and a water dispersant. branched polymer (binder); the branched polymer having an average molecular weight of approximately 5,000 to 1,000,000 and contains 20% to 80% by weight of a hydrophilic main chair and correspondingly 80% to 20% by weight of macromonomer side chains; the main chain being polymerized ethylenically unsaturated monomers and 2% to 30% by weight, based on the weight of the main chain, polymerized ethylenically unsaturated monomers having an acid-functional group; and where at least 10% of the groups with acid functionality are neutralized with an amine or an inorganic base and are hydrophilic in comparison to the side chains; and the side chains are made of polymerised ethylenically unsaturated monomers macromonomers that are polymerized in the main chain through an ethylenically unsaturated group and the macromonomers have a weight average molecular weight of approximately 1,000 to 30,000 and where the weight coefficient between the hydrophobic material and the binder is approximately 1/100 to 200/100.
