    Abstract: Viruses are selectively separated from an aqueous mixture of virus and nonviral protein by contacting the aqueous mixture with a water-insoluble polyelectrolyte polymer containing basic groups to selectively sorb the virus on the polymer and then if desired removing the polymer containing the virus from the aqueous mixture. The polyelectrolyte polymers are polycationic or polyampholytic in nature and contain imide groups selected from the group consisting of diloweralkylaminoloweralkylimide groupings and loweralkyliminodi(loweralkylimide) linkages as exemplified by crosslinked dimethylaminopropylimide derivatives of isobutylene/maleic anhydride copolymers.

    Abstract: The level of blood cholesterol in a living animal body in which a state of hypercholesterolemia exists is lowered by orally administering to said animal body a pharmaceutically effective amount of a polymer, which is (1) polymerized unsaturated carboxylic acid or anhydride, or (2) a copolymer of (a) an unsaturated monomer having, for Example, 2 to 30 carbon atoms and, (b) an unsaturated carboxylic acid, anhydride or derivative thereof as exemplified by octadecene-1/maleic anhydride copolymer. Polymers having lipophilic properties are a preferred class. A typical dosage is an amount which represents in the range of from about 0.01 to about 5.0% of the diet.

    Abstract: A process for making a continuous filament from discrete particulate matter including particles and fibers and mixtures thereof which may be initially packed and oriented in any random fashion. The particulate matter is added to a reaction vessel having a pair of electrodes therein. A strong electrokinetic field is established in this vessel and this electrokinetic field will untangle and properly orient the various random fibers and particulate matter through its influence. This action will cause close packing of the particulate matter in a desired pattern. Furthermore, the orientation is made to take place in a polymeric composition or resin matrix system so that the particulate matter is not only oriented, but held in the oriented position without the aid of the electrokinetic field. During the process of alignment and polymerization or partial polymerization, the continuous filament is formed and simultaneously removed outwardly from the vessel and then fully cured.
