摘要:
The invention relates to a process for producing coated solid dosage forms by forming a plastic mixture from at least one thermoplastic physiologically tolerated polymeric binder and at least one active ingredient and extruding the plastic mixture, wherein the extrudate is subsequently treated with at least one liquid or vaporized coating agent, and the coated extrudate is shaped to the required dosage form.
摘要:
A process for producing solid dose forms by mixing at least one polymeric binder, with or without at least one active ingredient and with or without conventional additives, and shaping the mixture, where at least one of the components is employed in liquid form.
摘要:
A solid or semisolid, at least two-phase active ingredient-containing formulation in which there is multiparticulate incorporation of one of the two phases into a matrix of the other phase, and at least one of the phases contains at least one active ingredient, obtainable by introducing particles of one phase into the other phase in a plastic state, and shaping the material while still plastic.
摘要:
A process for producing solid combination tablets which have at least two phases comprises molding a melt of a polymeric binder with or without at least one active ingredient, there being at least one solid product, which may contain an active ingredient incorporated into the still plastic composition during the molding step.
摘要:
Shear forces are used for essentially salt-free coagulation of plastics dispersions or rubber dispersions. For this, method of use is made of an apparatus with at least one shearing module which has a stator and a rotor arranged within the stator, where the surfaces facing toward one another in the stator and in the rotor are in each case smooth, or at least the rotor exhibits a structure formed on its surface and facing from this in the direction of the stator, and between the stator and the rotor there is a gap of predetermined gap width. The process is carried out by passing the dispersion to be coagulated through the gap between stator and rotor and precipitating the dispersion by rotation of the rotor with predetermined shear rate and shear deformation.
摘要:
Disclosed is a temperature controlled radiation transmission material for plural component films, the material being present in one or more cores allsidedly surrounded by a transparent sheath layer. The plural component films are particularly useful for the reversibly temperature dependent control of the radiation transmission of buildings and of technical facilities, especially solar energy apparatus, in the apparel industry and/or for decorative purposes.
摘要:
A process for the continuous production of polyamides from a mixture of at least one lactam and water and, if required, other monomer units and/or conventional additives and fillers under polyamide-forming conditions, where the mixture of the starting materials is heated in liquid phase in a first reaction zone until a conversion of at least 70% is reached, and undergoes adiabatic decompression and further polymerization in another reaction zone, wherein, in the first reaction zone, 0.5-7% by weight of water are employed, the temperature is increased to the range from 220.degree. to 310.degree. C., and polymerization is carried out until a conversion of at least 85% is reached and, in the second reaction zone, after the decompression further polymerization is carried out in the range from 215.degree. to 300.degree. C. without heat input.
