Abstract

"ESPUMA FLEXìVEL DE POLIURETANO, PROCESSO PARA PREPARAçãO DA MESMA, ESPUMA RìGIDA DE POLIURETANO, PROCESSO PARA PREPARAçãO DA MESMA, E, USO DO CO~ 2~ COMO MELHORADOR DO FLUXO DE AR". Processo para preparação de espumas rígidas e flexíveis de poliuretano pela reação de um poliisocianato e um poliol na presença de água e CO~ 2~. As espumas obtidas não apresentam significativa transição de vidro em temperaturas entre -100‹C e +25‹C e possuem propriedades de fluxo de ar melhoradas.
