Abstract

Patente de Invenção: <B>"MISTURA DE CIMENTO DE COMPOSIçãO DE CIMENTO"<D>. A invenção propicia: uma mistura de cimento que possui excelente de dispersão de cimento e que apresenta elevada retenção de maleabilidadel; e uma composição de cimento que possui excelente capacidade de dispersão de cimento e que apresenta elevada retenção de maleabilidade. A mistura de cimento compreende um ácido policarboxílico como um componente efetivo, em que o ácido policarboxílico é obtido por um processo que inclui as etapas de alimentar: "a" partes em peso de um polialquileno glicol (A) e "b" partes em peso de um monómero de ácido (met)acrílico (B) a um reator na faixa de {(a/n^ ¢^)/b} x 100 <243>200, em que n é um número molar médio dos grupos oxialquileno adicionados no polialquileno glicol (A) e é um número de 1 a 300; efetuar uma reação de esterificação da mistura resultante no reator, dessa forma obtendo um (met)acrilato de polialquileno glicol (C); e copolimerizar o (met)acrilato de polialquileno glicol (C) resultante e o monómero de ácido (met)acrílico (B), dessa forma obtendo o ácido policarboxílico.
