Abstract

POLÍMERO RAMIFICADO CONTENDO GRUPO SILANO. A invenção refere-se a um polímero ramificado contendo grupos silano que tem uma média de pelo menos 2,1 grupos silano por molécula, a partir da reação de (i) um polímero contendo grupos isocianato e tendo um teor de NCO dentro de uma faixa de 0,7% a 4% em peso, obtido a partir da reação de pelo menos um di-isocianato monomérico com pelo menos um poliéter poliol em uma razão molar NCO:OH de pelo menos 1,5/1, com (ii) pelo menos um amino-, mercapto- ou hidroxissilano, em uma razão estequiométrica de pelo menos um amino-, mercaptoou hidroxissilano por equivalente molar de grupos isocianato. O polímero contendo grupos silano é estável ao armazenamento, líquido à temperatura ambiente e fácil de manusear e permite composições curáveis com excelente processabilidade, cura rápida, alta resistência acoplada com boa extensibilidade e estabilidade térmica surpreendentemente boa. O polímero é particularmente adequado como um componente de vedantes, adesivos ou revestimentos curáveis por umidade, que em particular contêm adicionalmente um polímero adicional, em particular linear, contendo grupos silano.
