Hellmuth Wurm has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6949292
    Abstract: The invention relates to a method for producing defined layers or layer systems made of polymers or oligomers on any solid surface and with a controlled structure, according to which the layers are chemically deposited on the solid surface by means of living/controlled free-radical polymerization. Said method comprises the following steps: a) bonding the compounds of the general formula (a) A-L-I to the solid surface via the active group A, where A represents an active group, I is the initiating group for ATRP polymerization and L is the binding link between A and I; and b) carrying out living/controlled free-radical polymerization by reacting the initiator group I with monomers, macromonomers or mixtures able to undergo free-radical polymerization, which produces the polymer layer on the solid surface. The invention also relates to solid surfaces with oligomer or polymer layers and initiators for carrying out the method.
