  • Publication number: 20090069495
    Abstract: What are described are coating compositions comprising pigments and/or fillers and multistage polyvinyl ester dispersions as binders. These binders are produced by a selected multistage process in which a polyvinyl ester dispersion is obtained in a first stage, monomers in dissolved or pure form or in the form of an emulsion are added to the reaction mixture in a second stage and then the polymerization is started again. The polyvinyl ester dispersions comprise polymerized silanes and/or epoxides or the polyvinyl ester dispersions have only a small content of protective colloids, if any. The coating compositions formulated with the multistage polyvinyl ester dispersions obtained in this way are notable for a very high weathering resistance.

  • Patent number: 6867248
    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.

  • Patent number: 6841614
    Abstract: The invention relates to a method of producing soluble polymer granules which are suitable for use in washing and/or cleaning surfactants. According to said method, an aqueous preparation of the polymer which contains at least 30% by weight polymer, optionally in admixture with other washing and/or cleaning surfactant ingredients, is granulated and at the same time dried batchwise or continuously, preferably continuously, in a circular fluidized bed. In said fluidized bed, an eddy flow about the vertical axis of the apparatus is produced above the ground of the fluidized bed by means of an air inlet. The invention also relates to soluble, spherical polymer granules with a polymer content of 50 to 95% by weight and to washing or cleaning surfactants containing the inventive granules.
