摘要:
The invention relates to dental compounds that contain at least one polyacid or at least one polyacid and at least one salt of at least one polyacid. The polyacids used have at least one branch point in the polymer structure and are water-soluble and not cross-linked and their repeat units consist to at least 80 mole % of acrylic acid segments.
