Polymer-coated stents, processes for producing the same and their use for restenosis prevention

The present invention relates to methods of producing wool or animal hair material with improved properties such as shrink-proofed (anti-felting tendency), increased whiteness, improved dyeability, increased softness and/or reduced pilling tendency, the method comprising the steps of treating wool, wool fibers or animal hair material in a process selected from the group consisting of plasma treatment processes and the Delhey process, and subjecting the wool or animal hair material to a treatment with a proteolytic enzyme (a protease), preferably a serine protease, more preferably a subtilisin, in an amount effective for improving the properties.

Method for enzymatic treatment of wool

Process for the manufacture of polymers having repeating units comprising spiro orthoester groups of general formula (I), wherein A is C,-alkylene, C,-alkyleneoxycarbonyl or an oxygen-carbon bond, R,is hydrogen or methyl, R,is C,-alkyl or C,-alkyl substituted by C,-alkoxy or aryloxy, R,and R,independently are hydrogen or C,-alkyl, R,is hydrogen or methyl, R,is hydrogen, methyl, phenyl, carboxy, carboxy-C,-alkyl, carboxamido or cyano, n is an integer >1 and m is 0 or an integer &gE;1, with the proviso that the molecular weight of the polymer is between 500 and 1,000,000, the polymers obtained and their use specifically in dental filling materials.
