Abstract: In one aspect, amphiphilic block copolymers are described herein comprising a first block and a second block, the second block including monomer having a side chain comprising a heteroaryl moiety, wherein the second block is more hydrophobic than the first block. In some embodiments, the heteroaryl moiety is a five-membered ring or six membered ring. Amphiphilic block copolymers described herein, in some embodiments, can be used to form micellar compositions for solubilizing and delivering water insoluble pharmaceutical and/or therapeutic agents.

Abstract: Compositions for delivery having a biological agent or derivative thereof, and a poly(oxyethylene)-poly(oxypropylene) block copolymer. The compositions are useful in immunodeficiency infection virus therapy. The invention also encompasses methods of treatment using the same.

Abstract: A method and composition are disclosed for providing a two-part polymer binder additive for a fibrous sheet for improving both its strength and durability. The two-part polymer binder may be added to augment organic binders to increase board strength and durability or to reduce the amount of organic binder required. The polymers may also be added in place of conventional organic binders or added in addition to organic binders to improve sag resistance and fibrous sheet performance.
