Abstract
Un prepolímero terminado con isocianato, que contiene un agente de expansion, presurizado, que contiene grupos oxazolidona y uretano puede prepararse mediante la reaccion de un componente de isocianato con un componente de poliol, donde el componente de isocianato (A) empleado es un producto de reaccion que contiene grupos isocianato de extremo y obtenido mediante la reaccion de al menos un isocianato que contiene al menos dos grupos isocianato en la molécula con una mezcla de al menos un componente de al que contiene al menos dos grupos funcionales que reaccionan con isocianato y al menos un grupo epoxido en la molécula y un poliol de poliéster y el componente de poliol (B) empleado comprende al menos un poliéster terminado por grupos hidroxilo primarios y tiene una funcionalidad superior o igual a 2.
