Abstract (en)
[origin: EP0407906A1] 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.
