Abstract

"PROCESSO PARA PREPARAçãO DE PRé-POLìMEROS DE POLIURETANO POBRES EM MONÈMEROS". A presente invenção refere-se a um processo para preparação de pré-polímeros de poliuretano com grupos isocianato finais, no qual reagem-se poliisocianatos com polióis, sendo que (1) em uma primeira etapa de síntese, a) emprega-se, como poliisocianato, pelo menos um diisocianato assimétrico, b) emprega-se, como poliol, pelo menos um poliol com peso molecular médio (M~ n~) de 60 até 3000 g/mol, c) ajusta-se a proporção de grupos isocianato para grupos hidroxila na faixa entre 1,2:1 até 4:1, d) adiciona-se um catalisador, e após efetuada a reação (II) em uma segunda etapa de síntese e) adiciona-se pelo menos um outro poliol de modo que seja ajustada uma proporção total de grupos isocianato para grupos hidroxila na faixa de 1,1:1 até 2:1. Os pré-polímeros de poliuretano preparados deste modo são apropriados para preparação de adesivos e substâncias de vedação reativos de um e dois componentes, particularmente de adesivos de forração e como componente para preparação de adesivos de fusão. Os pré-polímeros de poliuretano preparados de acordo com a invenção são pouco viscosos, pobres em monómero e livres de subprodutos que usualmente resultam do processamento térmico para a retirada de monómeros de pré-polímeros de poliuretano.
