Abstract

PROCESSO PARA PRODUçãO CONTINUA DE ELASTOMEROS DE POLIURETANO PROCESSáVEIS TERMOPLASTICAMENTE, E, USO DE ELASTÈMEROS DE POLIURETANO TERMOPLáSTICOS. A invenção está relacionada a método para a produção contínua de elastómeros de poliuretano termoplasticamente processáveis e com homogeneidade melhorada, pelo qual um poliisocianato (A), um composto (B) com uma média de pelo menos 1,8 e de no máximo 3,0 átomos de hidrogénio com atividade Zerewitinoff, um peso molecular médio de 450 g/mol a 5000 g!mol, em uma proporção de 1 a 80 % equivalentes, em relação ao conteúdo de grupos isocianato no poliisocianato (A), um extensor de cadeia (C), com uma média de pelo menos 1,8 e de no máximo 3,0 átomos de hidrogênio com atividade Zerewitinoff por molécula, um peso molecular numérico médio de 60 g!mol a 400 g/mol, em uma proporção de 12 a 99 % equivalentes, em relação ao conteúdo de grupos isocianato do poliisocianato (A), O a 30 % em peso de catalisadores, em relação à quantidade total de elastómeros de poliuretano e outros adjuntos e aditivos (D), em uma relação molar NCO:OH de 0,9:1 a 1,2:1 do poliisocianato (A) para o total do composto (B), do extensor de cadeia (C) e dos outros adjuntos e aditivos, são alimentados a uma extrusora de duplo-parafuso auto-limpante, operada com uma alta velocidade de arrasto, sendo a mistura então descarregada da extrusora de duplo-parafuso auto-limpante para um dispositivo adicional para reação, caracterizado pelo fato de que na extrusora de duplo-parafuso auto- limpante, são ajustadas velocidades de arrasto acima de 6000 s^ -1^ e tempos de residência na faixa de 1 a 20 segundos.
