Abstract

"PROCESSO CONTìNUO PARA PREPARAçãO DE UM LáTEX DE POLIURETANO". Um látex de poliuretano/uréia/tiouréia tendo uma polidispersibilidade de peso molecular estreita e tamanho de partícula sub-micron pode ser preparando, inicialmente, um látex com teor de sólidos elevado (entre cerca de 65% e 74% de sólidos) de um pré-polímero de poliuretano/uréia/tiouréia, contatando então a emulsão com um reagente extensor de cadeia sob condições de modo a formar o látex do polímero.
