Water-in-oil emulsions, compositions, and methods that include a vinyl polymer that includes ethylene oxide-containing side chains and alkyl-Y-containing side chains, wherein Y is O or NR, wherein R is H or CH, and wherein the alkyl group of the alkyl-Y-containing side chain has at least 4 carbon atoms on average in a cyclic, branched-, or straight-chain configuration and optionally including one or more heteroatoms.

Wound filling compositions containing: (a) chitosan, (b) at least one compatible hydrocolloid material other than chitosan, and (c) water, exhibit a variety of properties desirable for use in filling large wound such as dermal ulcers, yet do not exhibit syneresis. Preferably compositions exhibit antimicrobial activity, would healing capability, a viscosity suitable to allow them to be applied to and remain in an open wound, and are able to absorb wound exudate.

Flexible magnetic recording media and stable-fluid, reactive dispersions of polymeric binder materials and particulate solids (either magnetic or non-magnetic) useful in preparing flexible or rigid magnetic recording media are provided. The use of a crosslinkable dispersing polymer comprised of a vinyl aromatic monomer and an ethylenically unsaturated monomer having hydroxyl functionality allows for magnetic media having both an excellent dispersion of finely divided magnetic particles, which improves the magnetic properties of the media, and an excellent set of mechanical characteristics, such as flexural modulus and tensile strength, of the magnetic media. The dispersing copolymer is used in an amount of at least about 5% by weight of the crosslinked binder mixture of which the crosslinkable dispersing polymer is a part.
