    摘要: Rigid or flexible circuits of electrically conductor tracks can be produced on flexible or rigid, non-conductive support materials bya) coating the surfaces of the support materials including existing drill holes with a primer and a conductive polymer, preferably poly-3,4-ethylendioxythiophene, which may contain binders,b) applying an electroplating resist in the form of the negative image of the conductor tracks,c) metallizing by electroplating the surface kept free by the electroplating resist, including existing drill holes, in the form of the positive image of the conductor tracks,d) removing the electroplating resist ande) removing the conductive polymer, which had been below the electroplating resist, or converting it to a non-conductive form, wherein the conductor tracks are electrically interconnected during the metallizing step by the layer of conductive polymer, thereby avoiding the need to individually contact each conductor track.

    摘要: Polyhydantoins of the type mentioned may be prepared by reacting initially in a first step, bis-glycine esters with between 1 and 2 moles of diisocyanate per mole of bis-glycine ester in a liquid reaction medium, and after forming the polyurea from this bis-glycine ester and the diisocyanate, by further reacting in a second step with an amount of a monoglycine ester equivalent to the residual amount of isocyanate end groups, and finally by carrying out the cyclocondensation to give the polyhydantoin by removing hydroxyl compounds.
