The present invention generally relates to methods and friction-reducers for decreasing the friction of a fluid. More specifically, the method comprises contacting a friction-reducer to reduce the friction of a fluid flowing in a conduit. The friction-reducer comprises an emulsion polymer, comprising polyanion, polycation, and polynonionic monomers, and a highly concentrated salt solution.

Friction-reducing compositions formulated with highly concentrated brine

In an embodiment, the present disclosure pertains to a method and compositions for modification of medical devices, such as indwelling medical devices, implantable catheters, in particular, urinary catheters, to enhance formation of a high density and stable biofilm comprising non-pathogenic organisms for the treatment and prevention of colonization of pathogens leading to device-associated infections, such as urinary tract infections. In some embodiments the present disclosure also relates to a method and compositions for storage and use of the catheters coated with a non-pathogenic biofilm. In some embodiments the present disclosure also pertains to a method and compositions for modification of implantable medical devices with bacterial resistant polymers, and/or antimicrobial agents.
