    Abstract: Polymers, and particularly conventional commodity bulk polymers, are modified to have a surface activity of interest using a surface modifying polymer that includes a moiety that favors migration to the surface of the bulk polymer together with a moiety provides the activity of interest (e.g., biocidal, wettability modifying (hydrophobic or hydrophilic), resistance to radiant energy, providing a functional group for functionalizing the surface, etc.). The surface modifying polymer is combined with the bulk polymer, and, due to the presence of the moiety that favors migration, concentrates primarily on the surface of the bulk polymer such that the moiety that provides the activity of interest is located primarily on the surface of the bulk polymeric article which is produced. Advantageously, only a minimal amount (such as, e.g., about 2 weight %) of polymeric surface modifier is needed. Being able to achieve desired properties (such as biocidal activity, wettability modification, etc.) without needing much polymeric surface modifier is highly advantageous.

    Abstract: The invention discloses a method for determining the air content of the brake fluid in a hydraulic braking system. This method also permits determining the quality of the bleeding of the braking system. The principle of the method is a comparison of the volume intake with the respectively achieved pressure. The correlation is compared to nominal values. As the volume intake is determined by the clearance, the system is set by means of a pre-actuation to an initial condition before each actual measurement.
