Abstract

ELASTOMEROS DE POLIURETANO Y DE POLIUREA PREPARADOS MEDIANTE LA REACCION EN UN MOLDE CERRADO DE UNA COMBINACION DE REACCION, QUE CONSTA DE UN POLIISOCIANATO Y DE UN POLIETER DE PESO EQUIVALENTE RELATIVAMENTE ALTO. EL PROCESO SE CARACTERIZA POR EL EMPLEO COMO DICHO POLIETER DE UN POLIMERO O COPOLIMERO DE OXIDO DE PROPILENO CON AL MENOS DOS GRUPOS HIDROXILOS POR MOLECULA, UN PESO EQUIVALENTE DE 1000-5000 Y UN CONTENIDO DE TIPO MONOFUNCIONAL CERCANO AL 0,04 MILIEQUIVALENTE POR GRAMO (MEQ G) DE POLIMERO O MENOS.
