Abstract
La invencion da a conocer una nueva clase de agentes tensoactivos de silicona y su empleo para la preparacion de una espuma flexible de uretano. Los agentes tensoactivos incorporan poliéteres de alto peso molecular, preparados con distribuciones del peso molecular más estrechas que los poliéteres convencionales. Estos poliéteres se preparan usando un catalizador de cianuro de doble metal ("DMC"). Estos agentes tensoactivos son mejores estabilizadores de la espuma en comparacion con los agentes tensoactivos análogos, preparados de poliéteres convencionales.
