Abstract

PROCESSO PARA A PRODUçãO DE PRé-POLìMEROS DE POLIURETANO. A presente invenção refere-se a um processo para a produção de pré-polímeros de poliuretano com grupos isocianato em posição terminal, no qual reagem-se pol´isocianatos com polióis, sendo que (1) em um primeiro estágio de síntese se produz um componente (A), em que a) se utiliza como poliisocianato (X) pelo menos um pol´isocianato assimétrico, preferentemente do grupo: toluilenodisocianato (TDI) com um teor>igual 99% em peso, de 2,4-TDI,2,4'-difenilmetanodiisocianato com uma fração de 2,4'-isómeros de pelo menos 95% em peso, preferentemente pelo menos 97% em peso, b) como poliol pelo menos um poliol com um peso molecular médio (M~ n~) de 60 até 3000 g/mol, c) a proporção de grupos hidroxila para grupos isocianato é ajustada para < 1, preferentemente na faixa entre 0,4: 1 até 0,8: 1, de modo especialmente preferido, na faixa entre 0,45: 1 até 0,6: 1, d) eventualmente se acescenta um catalisador e após a reação de todos os grupos hidroxila (II) em um segundo estágio de síntese se acrescenta um outro poliol ao componente (A), sendo que se ajusta a proporção de reação dos grupos hidroxila do outro poliol para grupos isocianato do componente A na faixa de 1,1 :1 até 2,0 :11 preferentemente de 1,3 :1 até 1,8:1 e de modo especialmente preferido, na faixa de 1,45 :1 até 1,75 :1. Pré-polímeros de poliuretano produzidos dessa maneira prestam-se para a fabricação de adesivos e materiais de vedação de um e dois componentes, especialmente de adesivos de revestimento, Os pré-polimeros de poliuretano produzidos de acordo com a invenção, são pouco viscosos e pobres em monómeros.
