Bifunctional viscosity modifiers for petroleum products based on amine-containing copolymers of higher alkyl (meth)acrylates

Copolymers of amine-containing methacrylic monomers with higher alkyl (meth)acrylates was shown to be efficient viscosity modifiers for heavy crude oils and mineral oils. They also exhibit additional properties of inhibitors of asphaltene-resin-paraffin deposits (in crude oils) and dispersant additives (in mineral oils). A comparison of efficiency was done for copolymers with different structure and amino units content.
