    摘要: The invention relates to polyfunctionally reactive polymeric substances which contain at least two structural units of the general formulae (I) and/or (II) in the molecule and whose polymer backbone linkages are C—C bonds, ether bonds, urethane bonds, amide bonds, ketone bonds or combinations thereof. The substances are useful as binders for various applications.
