    Abstract: The present invention relates to a method of preparing porous solids, which method comprises polymerizing, in a salt melt or a eutectic mixture of salt melt containing at least one Lewis acidic salt, cyano monomers having at least one or at least two cyano groups in their molecule, wherein the at least one or at least two cyano groups are bonded to a rigid linking group in the cyano monomer, as well as to the porous solids obtainable by that method. Owing to their porosity and the associated extremely high specific surface area, the porous solids are useful as sorbents, filtering and insulating materials, as well as catalyst carriers.

    Abstract: A porous polymeric matrix containing at least one natural polymer and at least one synthetic polymer and optionally at least one cation. Furthermore, a method of making a porous polymeric matrix involving mixing at least one natural polymer and inorganic salts with a solution comprising at least one solvent and at least one synthetic polymer to form a slurry, casting the slurry in a mold and removing the solvent to form solid matrices, immersing the solid matrices in deionized water to allow natural polymer cross-linking and pore creation to occur simultaneously, and drying the matrices to create a porous polymeric matrix; wherein the matrix contains a cation. Also, a method of making a porous polymeric matrix, involving mixing at least one natural polymer in an aqueous solvent and mixing at least one synthetic polymer in an organic solvent, combining the mixtures and casting in a mold, and separately removing said aqueous solvent and said organic solvent to form a porous polymeric matrix; wherein the porous polymeric matrix does not contain a cation.

    Abstract: Biocompatible polyhydroxyalkanoate compositions with controlled degradation rates have been developed. In one embodiment, the polyhydroxyalkanoates contain additives to alter the degradation rates. In another embodiment, the polyhydroxyalkanoates are formed of mixtures of monomers or include pendant groups or modifications in their backbones to alter their degradation rates. In still another embodiment, the polyhydroxyalkanoates are chemically modified. Methods for manufacturing the devices which increase porosity or exposed surface area can be used to alter degradability. For example, as demonstrated by the examples, porous polyhydroxyalkanoates can be made using methods that creates pores, voids, or interstitial spacing, such as an emulsion or spray drying technique, or which incorporate leachable or lyophilizable particles within the polymer. Examples describe poly(4HB) compositions including foams, coatings, meshes, and microparticles. As demonstrated by the examples, these polyhydroxyalkanoate compositions have extremely favorable mechanical properties, as well as are biocompatible and degrade within desirable time frames under physioogical conditions. These polyhydroxyalkanoate materials provide a wider range of polyhydroxyalkanoate degradation rates than are currently available. Methods for processing these materials, particularly for therapeutic, prophylactic or diagnostic applications, or into devices which can be implanted or injected, are also described.
