1) Polyester resins are the condensation products of polybasic acids and polyols.

2) This invention relates to glycerinoid polybasic alcohol compositions which are solid or liquid compositions composed of sorbitol and diglycol, 1,3-butanediol or 1,4-butanediol.

3) Objective To analyze polybasic acids and higher fatty acids Rosa roxburghii Tratt fruit.

4) Experiment shows, polymer polybasic alcohol can effectively enhance the compressive stress of polyamine soft foam plastic.

5) Objective To analyze polybasic acids and higher fatty acids of Rosa roxburghii Tratt fruit.

6) Simulated sample and mixed reaction solution of polybasic acids are analyzed in comparison with the results of ion-chromatography. The calculation error is less than 7%.

7) By using sulfobetaine derivant as leveling agent and polybasic acid as complexant of interfering ions, the brightener SN-1 for nickel plating is developed.

8) Objective: Quantitative analysis of four polybasic alcohols and condensation alcohols.

9) Simulated sample and mixed reaction solution of polybasic acids are analyzed in comparison with the results of ion-chromatography.

10) Eleven kinds of polybasic acids and higher fatty acids of 39 samples of flue-cured tobacco in Yunnan and 2 overseas samples in 2004 were classified by the method of cluster analysis.

11) The compressive stress of general polyamine soft foam plastic is improved with polymer polybasic alcohol.

12) There are three essential kinds of scale inhibitors: amino - multi - carboxylate,(http:///polybasic.html) organic polybasic phosphonic acid and polymeric compound.

13) The poly compound mostly exists in eutectic crystal shape or polybasic point shape.
