POLYMERIC COMPOSITIONS COMPOSED OF ETHYLENE-VINYL ESTER COPOLYMERS ALKYL (METH)ACRYLATES, PROCESSES FOR PRODUCTION THEREOF AND USE THEREOF AS POUR POINT DEPRESSANTS FOR CRUDE OILS, MINERAL OILS OR MINERAL OIL PRODUCTS

摘要

The invention relates to polymer compositions obtainable by radical polymerization of at least two different alkyl(meth)acrylates in the presence of at least one ethylene-vinyl ester copolymer, wherein a mixture comprising alkyl(meth)acrylates with linear C12 to C60 alkyl groups and alkyl(meth)acrylates different therefrom with linear C1 to C11 alkyl groups and/or branched C4 to C60 alkyl groups and/or cyclic C5 to C20 alkyl groups is used as the alkyl(meth)acrylates. The invention further relates to the use of such polymer compositions as pour-point depressants for crude oils, mineral oils or mineral oil products.
