1. Supermolecules can be synthesized through self-assembly of polyacid(A)and modified polyether(B).

2. Macromolecule monomer with active groups is polycondensated with polyacid and polyols through esterification reaction to give saturated polyester that is well compatible with acrylic resin.

3. And the influence of needed catalyst and polyacid dosage on resin performances is discussed.

4. This article has described the production of water-soluble alkyd resin and the formulation of pigmented paint, and discussed the choice of polyacid, polyols, co-solvents and additives.

5. The principle and method of producing XDB-1 type of unsaturated polyester resin from waste PET bottles as the main raw material and polyacid and polyalcohol as auxiliary material were studied.

6. In process of synthesizing N oxidized pyridine, rare earth hetero polyacid was used as catalyst and extortion was canceled.
