Abstract (en)
[origin: EP0137397A2] 1. An acidic galvanic copper bath for the deposition of fine-grain ductile copper, comprising contents of polymers derived from bifunctional propane derivatives and optionally other bath additives, characterized in that it contains bifunctional propane derivatives represented by the formulae I and/or II, wherein X and Y each represent a hydroxyl group or halogen, X and Y are different, and Z represents oxygen, sulfur or a methylene group, see diagramm : EP0137397,P5,F1 see diagramm : EP0137397,P5,F2 which have been polymerized in the presence of from 1 to 50% by mole of one or more unsaturated alcohols having from 3 to 10 carbon atoms and one or more double bonds and/or triple bonds at a temperature of from 100 degrees C to 260 degrees C.
