ABSTRACT:
New copolymers, mixtures thereof with poly(meth)acrylate esters and the use thereof for improving the cold fluidity of crude oils.
Copolymers comprising as comonomers therein from 50 to 99.9% by weight of a C.sub.14 -C.sub.22 -alkyl(meth)acrylate and 50 to 0.1% by weight of a comonomer derived from a compound comprising a single polymerizable C.dbd.C group and these copolymers or their mixture with C.sub.14 -C.sub.22 -alkyl poly(meth)acrylates having enhanced pour point depressant properties.
