Abstract

"PROCESSO PARA A PREPARAçãO DE ARTIGOS MOLDADOS DE POLIURETANO MACIçOS". A presente invenção refere-se a um novo processo para a preparação de artigos moldados de poliuretano maciço, o qual com base na alta rigidez própria podem apresentar espessuras de parede finas bem como uma complexa geometria. Os artigos moldados de poliuretano de acordo com a invenção, podem ser preparados pela reação de poliisocianatos escolhidos com compostos escolhidos com grupos capazes de reação com relação aos grupos isocianato pelo processo de fundição, isto é, com uma tecnologia de elaboração simples e económica.
