Abstract

Una composicion lubricante comprende un aceite de base y un modificador de la viscosidad que incluye un interpolímero de etileno/alfa-olefina. El interpolímero de etileno/ alfa-olefina es un copolímer en bloque que posee por lo menos un bloque duro y por lo menos un bloque blando. El bloque blando comprende una cantidad superior de comonomeros que el bloque duro. El copolímerode bloque posee una serie de características unicas descriptas en la presente. Dichos copolímeros en bloque ofrecen la posibilidad de un mejor desempeno a baja temperatura y mejor flexibilidad en la formulacion del aceite para motores, lubricantes para engranajes y grasas, etc.
