Abstract

"ESPUMAS DE POLIURETANO DE BAIXA EMISSãO DE AMINA E PROCESSO PARA PREPARá-LAS". Descobriu-se que se pode obter uma espuma de poliuretano tendo emissões de amina desprezíveis ou, significativamente reduzidas reagindo um poliol com um poliisocianato na presença de um agente de expansão sendo um carbamato obtido contatando dióxido de carbono com uma amina ou alcanolamina, e ainda na presença de um catalisador de amina não fugitivo. Divulga-se um processo particularmente útil na preparação de espuma de película integral, tal como volante de direção de automóvel, exibindo desempenho físico atraente, e baixas emissões de amina volátil.
