Abstract

"PROCESSO PARA FORMAçãO DE PRé-POLìMERO FUNCIONAL EM ISOCIANATO POSSUINDO UM BAIXO TEOR DE ISOCIANATO RESIDUAL". E proporcionado um processo para formação de um pré-polímero funcional em isocianato possuindo um baixo teor de isocianato residual, que compreende (a) reagir um poliol selecionado do grupo que consiste de poliéter polióis, poliéster polióis, poliéster poliéter polióis, acrílicos polióis, glicóis e misturas dos mesmos, com um monómero de isocianato para formar uma mistura de reação compreendendo um pré-polímero com um teor de NCO na faixa de 2,5 a 11,5% em peso, e uma funcionalidade em NCO na faixa de 2,0 a 4,0; e (b) conduzir a mistura da reação compreendendo o pré-polímero e o isocianato não reagido através de um evaporador de percurso curto para remover o isocianato não reagido até um nível de menos de 0,15% em peso. De preferência, o evaporador de percurso curto é operado a uma pressão na faixa de 0,1 a 10 Pa, e possui uma temperatura no condensador na faixa de 25 a 75<198>C.
