Abstract
Polímeros terminados en oximinosilano, los cuales, cuando curan a la temperatura ambiente, llegan a ser elastomeros estables. Los primeros tiene un grupo de cetoximino-sililo hidrolizable en cada extremo de cada molécula y se preparan por la reaccion de un polímero líquido terminado en hidroxilo con un diisocianato orgánico, para producir un pre-polímero terminado en isocianato. El prepolímero resultante es luego convertido en un polímero terminado en mercaptano, por la reaccion con un mercaptoalcohol o por la reaccion con un alcohol o una amina olefínicos de alquileno, para dar un polímero terminado en olefina, el cual luego se hace reaccionar con un dimercaptano. Cuando el polímero terminado en mercaptano se hace reaccionar con un vinil-oximino-silano o un vinilalcoxi-oximinosilano, se obtiene un polímero líquido terminado en silano. Tales polímeros tiene propiedades mejoradas del alargamiento, resistencia a la humedad, resistencia a la tension y al desgarre en formulaciones de adhesivos, recubrimientos y selladores.
