Poly(alkyl (meth)acrylate) depressants for paraffin oils

The peculiarities of synthesis of higher poly(alkyl (meth)acrylate)s bearing C₁₆–C₂₆ alkyl fragments are considered, and a comparison of their functioning as depressants for paraffin oils from different deposits is carried out. It is shown that the highest efficiency in oils under study is manifested by the sample of C₁₆–C₂₀ poly(alkyl acrylate) with a weight-average molecular mass of 70000.
