Abstract: The disclosure relates to compositions and methods useful for treating a substrate, for example for preventing or inhibiting corrosion of metal substrates. The compositions comprise (a) at least one cross-linkable, partially hydrolyzed polymer, and (b) at least one particular crosslinking agent.

Abstract: Methods and compositions for providing long term pain relief in, for example, surgery recovery, including injecting a composition comprising a plurality of microparticles having different sizes and at least one local anesthetic loaded into the microparticles at different loading levels. Extended prolonged blockage of nerve action in sheep testing was confirmed. Some of the microparticles comprise a high loading of local anesthetic. Testing in sheep showed nerve blockage for at least six days.

Abstract: A microencapsulatable solvent adhesive composition for coupling plastic conduits, such as pipes, connectors and related fittings comprises a water-insoluble polymer and a mixture of volatile organic solvents for the polymer, each of the solvents having 6 to 40 carbon atoms. This solvent adhesive composition is suitable for microencapsulation by aqueous-based microencapsulation processes. A plurality of microcapsules encapsulating the solvent adhesive composition are bound to a polymeric surface of a conduit, such as a pipe connector or fitting, by a binder composition, to form a surface coated with a layer of rupturable microcapsules. When the microcapsules are ruptured upon joining of the coated conduit to a second conduit, the volume of the released solvent adhesive composition is sufficient to cement the surfaces together.
