摘要： Embodiments of the present disclosure include modified nonionic surfactant formulations having a nonionic surfactant and a pour point depressant, where the modified nonionic surfactant formulations have a pour point of −3° C. to −54° C. In one or more embodiments, the modified nonionic surfactant formulations can be introduced into a flow of carbon dioxide, where the flow of carbon dioxide and the modified nonionic surfactant formulation are injected into an oil containing reservoir. In one or more embodiments, an emulsion of the carbon dioxide and the nonionic surfactant form in the oil containing reservoir, where the use of the pour point depressant provides minimal interference in forming the emulsion.

摘要： The present invention provides processes for making higher molecular weight, functionalized poly(meth)acrylamide polymer products. As an overview, the processes use (trans)amidation techniques in the melt phase to react one or more high molecular weight amide functional polymers or copolymers with at least one co-reactive species comprising at least one labile amine moiety and at least one additional functionality other than amine functionality. In practical effect, the processes of the present invention thus incorporate one or more additional functionalities onto an already formed or partially formed polymer rather than trying to incorporate all functionality via copolymerization techniques as the polymer is formed from constituent monomers. The methods provide an easy way to provide functionalized, high molecular weight poly(meth)acrylamide polymer products.
