    摘要: A medical device which can be introduced into the body tissue of a human or animal comprises a matrix of a polyurethane elastomer with organic silicone polymer units built into the main polymer chain and an oligodynamic agent spatially distributed uniformly within the matrix. The oligodynamic agent releases bacteriocidal or microbicidal metal ions when exposed to body tissues. The method for manufacturing the medical device is characterized by the addition of the oligodynamic agent in a solid or dissolved form prior to the reaction of the educts with isocyanate.

    摘要: A process for the manufacture of polymeric compounds which have any desired number of functional end groups. In this process, polyfunctional organoalkali metal compounds which have been manufactured by reaction of divinylbenzene with low molecular weight organoalkali metal compounds, are reacted direct, or after prior reaction with anionically polymerizable monomers, with reactive low molecular weight compounds. The polymeric compounds which have functional end groups can be employed, for example, as emulsifiers, secondary dispersions, secondary dispersing agents or polymeric carrier substances.

    摘要: A water-dispersed film-forming vehicle suitable for lacquers is disclosed. The vehicle consists of an aqueous dispersion of an air-drying alkyd resin dispersed by the use of a surfactant consisting of an adduct of allyl glycidyl ethers and ethylene oxide units onto a hydrophobic aliphatic radical having a replaceable hydrogen atom, optionally substituted by an aryl radical. The hydrophobic aliphatic radical may be a fatty-acid radical of from 6 to 26 carbon atoms and the aryl substituent is a phenol. The adduct includes 2 to 10 allyl glycidyl units and 5 to 25 ethylene oxide units per mol. The water-based dispersion diluent in which the alkyd resin is dispersed may include pigments, siccatives for the alkyd drying resin and optionally processing-aid solvents.
