Abstract
La presente invención se refiere a una composición de poliol para producir espumas rígidas de poliuretano, caracterizada porque comprende un componente de poliol que contiene un poliol que tiene la fórmula general en donde R1 representa independientemente un grupo etileno o un grupo propileno, y los dos grupos que contienen R1 están en la posición meta u orto entre sí; m y n son números mayores que 1, respectivamente, y su suma está en el rango de 3-40; y R' representa un hidrógeno o un grupo alquilo inferior, en cantidades de 20 a 50 por ciento en peso, con base en el componente de poliol en la composición de poliol.
