## Abstract D(+) tartaric acid is incorporated into glassβionomer cements to control the setting properties. ^13^C NMR spectroscopy of the fluid cement pastes have shown that tartaric acid reacts more readily than the polyacid with the glass, and hence suppresses the premature gelation of the cemen
Hyperbranched polymers are highly branched macromolecules that are prepared through a one-step polymerization process. Many kinds of hyperbranched polymers have been investigated as novel dendritic macromolecules. The general concepts, syntheses and the properties of hyperbranched polymers are revie
## Abstract Phosphorusβ31 nuclear magnetic resonance spectroscopy of phosphoric acid solutions containing zinc and aluminium indicates that zinc forms simple salts in solution, whereas aluminium forms a number of complexes, some of which are polymeric. The formation of the aluminophosphoric acid co
