Abstract: A process for producing pellets comprising biologically active substances in which the biologically active substances are homogeneously dispersed in a matrix based on at least one thermoplastic polymer, which polymer has in aqueous medium a pH-dependent solubility, by homogeneous mixing of the starting materials in the melt and subsequent extrusion and shaping, which comprises the shaping being performed in a cooling medium in which the pellets are not soluble or dispersible.

Abstract: The invention relates to a method of producing oily suspensions of water-soluble vitamins which comprises

Abstract: Solid formulation of a crop protection product can be obtained by melt extrusion and shaping of a mixture consisting of: 0.1-80% by wt. of an active ingredient which can be used in crop protection, or of a combination of such active ingredients, 10-80% by wt. of at least one mineral filler, 0-20% by wt. of inorganic or organic additives, and to 100% by wt.

Abstract: Solid dosage forms are obtained by mixing at least one polymeric binder, at least one active ingredient, and, where appropriate, conventional additives to form a plastic mixture, and shaping, using as polymeric binder a copolymer of an N-vinyllactam and a copolymerizable monomer having a hydrophobic radical. Dosage forms which show slow release of the active ingredient are obtained in a simple and low-cost manner.

Abstract: Insoluble, only slightly swellable popcorn polymers containing a) from 50 to 99% by weight of styrene and/or at least one monounsaturated styrene derivative, b) from 0.1 to 40% by weight of at least one N-vinyllactam or N-vinylamine and c) from 0.1 to 10% by weight of at least one difunctional crosslinking component, the stated percentages by weight of the individual components a) to c) summing to 100%.

Abstract: A process for preparing liquid iodophores with poly-N-vinyllactams and dextrins as carrier materials, which comprises heating a mixture of the carrier materials, iodine and iodide ions or, in place of the iodide ions, a reducing agent in aqueous medium in the presence of a monohydric or polyhydric alcohol having 1 to 6 carbon atoms at from 40 to 100° C.

Abstract: An apparatus and method for dispensing fine particle material from a container such as a flexible intermediate bulk container. The invention includes a dispensing assembly that has a dispensing device that is secured to an outlet tube of the container. Securement is achieved by a strap member wrapped about the container's outlet tube and a clamping casing and/or by an inflatable member that expands outward from the clamping casing. The casing surrounds a transport tube which is axially shiftable following securement of the clamping casing to the outlet tube. A head piece with gas cavity and radial and oblique extending ports is provided at the end of the transport tube. The dispensing device is inserted into the outlet tube below a blocking member provided at the base of the outlet tube. Following attachment of the outlet tube to the clamping casing, the blocking member is released. The transport tube is then released from a first position, shifted and then fixed in a second position.
