MINERAL OIL HAVING IMPROVED FLOW CHARACTERISTICS AND MINERAL OIL PRODUCT THEREFROM

摘要

The invention relates to mineral oils and mineral oil products of improved flow behaviour, from the group of crude oils, vacuum gas oils or residual oils, having a content of long-chain polyalkyl (meth)acrylates, the long-chain polyalkyl (meth)acrylates representing a mixture of A) a polyalkyl (meth)acrylate P1 having crystallisation starting temperatures above 15 degrees C (measured as the cloud point of a 0.1 % solution in isooctane) and B) a polyalkyl (meth)acrylate P2 having crystallisation starting temperatures at or below 15 degrees C, with the proviso that there is a temperature difference of at least 5 degrees C between the start of the crystallisation of the polyalkyl (meth)acrylates P1 and the start of the crystallisation of the polyalkyl (meth)acrylates P2.
