A composition for use as a multifunctional wax dispersant can treat subterranean formations for the recovery of oil and gas from oil and gas wells. A process can be used for the preparation thereof. A method for treating a crude oil with a wax dispersant composition according to the present invention reduces interfacial tension between the crude oil and the treatment fluids in the recovery of oil and gas from crude oil and gas wells.

Multifunctional wax dispersant for subterranean chemical applications

A method for the preparation of homo- and copolymers of alkyl (meth)acrylates having a low residual monomer content involves preparing a reaction mixture containing monomers, charging the reaction mixture, heating the reaction mixture, adding an additional monomer after initial monomer conversion, and optional further processing of the reaction mixture. The homo- and copolymers of alkyl (meth)acrylates obtained by this method as useful in lubricant applications.
