Abstract
Se polimerizan isocianatos fácilmente al polimerizar isocianatos alifáticos y/o aromáticos en presencia de metalocenos a temperaturas de 20 a 220 degree C, dado el caso a presion elevada o reducida y, dado el caso, en presencia de un disolvente orgánico inerte, empleándose los metalocenos en una cantidad de 5 a 50.000 ppm, referida a la cantidad de isocianatos empleados.
