Abstract
Abstract Oligomeric or prepolymeric organic compounds that contain both polymerizable unsaturated groups and acid radicals, their salts, or their reactive-derivative radicals. The compounds exhibit outstanding adhesion properties, especially to biological substrates, and are appropriate for application as bonding agents, adhesive filling materials, or adhesive cements in the fields of dentistry and medicine.
