Novel poly(carboxylates), partially amidated poly(acry late), poly{[1‐carboxylate‐2‐( N ‐ t ‐butyl)carbamoyl)]ethylene‐ alt ‐ethylene}, poly[1‐( N ‐oxysuccinyl‐aminomethenyl)ethylene], poly[1‐( N ‐oxymalenyl‐aminomethnyl)ethylene] and poly[1‐( N ‐oxyphthalyl‐aminomethnyl)ethylene] with intramolecular NH…O hydrogen bond between amide NH and coordinating oxygen were synthesized as model ligands for CaCO 3 biominerallization. The FE/SEM and its backscatter of the CaCO 3 composite of gold colloid‐conjugated poly{[1‐carboxylate‐2‐( N ‐ p ‐methylthiophenyl)carbamoyl]ethylene‐ alt ‐ethylene} indicate that the polymer ligand is located at the surface of vaterite crystals and the oriented carboxylate ligands control the CaCO 3 polymorph.
