    Abstract: Devices formed of or including biocompatible polyhydroxyalkanoates are provided with controlled degradation rates, preferably less than one year under physiological conditions. Preferred devices include sutures, suture fasteners, meniscus repair devices, rivets, tacks, staples, screws (including interference screws), bone plates and bone plating systems, surgical mesh, repair patches, slings, cardiovascular patches, orthopedic pins (including bone filling augmentation material), adhesion barriers, stents, guided tissue repair/regeneration devices, articular cartilage repair devices, nerve guides, tendon repair devices, atrial septal defect repair devices, pericardial patches, bulking and filling agents, vein valves, bone marrow scaffolds, meniscus regeneration devices, ligament and tendon grafts, ocular cell implants, spinal fusion cages, skin substitutes, dural substitutes, bone graft substitutes, bone dowels, wound dressings, and hemostats. The polyhydroxyalkanoates can contain additives, be formed of mixtures of monomers or include pendant groups or modifications in their backbones, or can be chemically modified, all to alter the degradation rates. The polyhydroxyalkanoate compositions also provide favorable mechanical properties, biocompatibility, and degradation times within desirable time frames under physiological conditions.

    Abstract: The present invention provides a process for producing alveolar cellulosic products (sponges, sponge-cloths, etc.) from a cellulosic raw material, the process comprising:at least partially dissolving a cellulosic raw material in an intrinsic solvent for cellulose;incorporating an effective quantity of at least one pore-forming agent into the resulting mixture, with mixing; said pore-forming agent(s), being compatible with the cellulosic mixture, being capable of generating macro- and micro-pores when it/they is/are actuated;gelling the homogeneous dough thus obtained;treating said gelled dough under conditions in which the cellulose precipitates out and the pore-forming agent(s) present are actuated.The process is an advantageous alternative to the viscose process which is a polluting process. The properties of the products obtained are completely similar to those of products obtained using the viscose process. The (novel) products form part of the invention.

    Abstract: A microporous polymeric film of high porosity comprises a halopolymer in which the repeating units are --(C.sub.n H.sub.2n)-- and --(C.sub.m X.sub.2m)-- in which each X independently represents fluorine or chlorine and the values of n and m are greater than one and less than six. The film is the result of firstly melt processing a mixture of the halopolymer, more than 150 parts by weight of an extractable salt and not more than 80 parts by weight of an extractable polymer per 100 parts by weight of the halopolymer, the extractable polymer not being completely and homogeneously mixed with the halopolymer and being less viscous than the halopolymer when both are molten so that the surfaces of the film resulting from melt processing are rich in the extractible polymer, and secondly extracting at least some of the extractable salt to render the film porous and extracting at least some of said polymer to impart surface porosity to the film. The film has a porosity of more than 50% by volume and more usually 60-70%. The film may be used as the separator of an electrochemical cell e.g. a battery having a lithium anode and a thionyl chloride electrolyte.

    Abstract: A composition and method for the controlled release of compounds from a plastic dispenser, usually a thermoplastic, generally in association with a porosigen in contact with water, for example, an aquatic environment or soil mixture. Thermoplastic dispensers are generally made from a water insoluble polymer such as polyethylene, polypropylene, ethylene vinyl acetate, polyamide, polystyrene, polyvinyl acetate, polyurethane, etc. Thermoset plastics, such as epoxy, are also used. The porosigen, depending upon the desired end use and release rate of a compound, can have a solubility of less than 0.1 or 0.001 grams per 100 grams of water, or up to 100 grams per 100 grams of water. The released compound, for example, a herbicide, is contained in the thermoplastic dispenser. The combination of the plastic dispenser containing the porosigen and compound results in a slow release of a herbicide which can last for days, months, and even years, through dissolution of the porosigen and the formation of a porous network permitting water to contact the dispersed herbicide located in the interior portions of the dispenser.

    Abstract translation: 一种组合物和方法，用于从塑料分配器（通常为热塑性塑料）中控制释放化合物，该塑料分配器通常与与水接触的孔隙菌素例如水生环境或土壤混合物结合。 热塑性分配器通常由水不溶性聚合物如聚乙烯，聚丙烯，乙烯 - 乙酸乙烯酯，聚酰胺，聚苯乙烯，聚乙酸乙烯酯，聚氨酯等制成。热固性塑料如环氧树脂也被使用。 取决于化合物的期望最终用途和释放速率的porosigen可以具有小于0.1或0.001克/ 100克水的溶解度，或至多100克/ 100克水。 释放的化合物，例如除草剂，包含在热塑性分配器中。 含有porosigen和化合物的塑料分配器的组合导致通过溶解porosigen并形成允许水与分散的除草剂接触的多孔网络，可以持续数天，数月甚至数年的除草剂的缓慢释放 位于分配器的内部。
