Abstract

"DISPERSãO AQUOSA". São descritas dispersões aquosas, tendo uma mínima temperatura de formação de película, não maior do que cerca de 50<198>C, que incluem um polimero em emulsão de multi-estágios, produzido por um processo que inclui um primeiro estágio de polimerização, em que uma primeira mistura monomérica, tendo uma temperatura de transição vítrea calculada de pelo menos cerca de 50<198>C, é polimerizada via polimerização por radical livre em emulsão, para obter-se um polímero em emulsão de primeiro estágio e um segundo estágio de polimerização, em que uma segunda mistura monomérica, tendo uma temperatura de transição vítrea calculada de cerca de -30<198>C a cerca de 10<198>C, é polimerizada via polimerização por radical livre em emulsão, na presença do polímero em emulsão de primeiro estágio. As dispersões são úteis em uma variedade de composições de revestimento, que exibem melhorada resistência de bloco.
