| Abstract: | A granular distribution meter,a whiteness meter,a electronic micrograph and DSC were used to determining powder polyamide prepared by precipitation in four solvents in this article.The results showed that the diameter of the powder,surface per gram and whiteness were different in the four ways. The powder had porous structure by means of the mixture solvent of alcohol and calcium chloride.The powder had high heat stability by means of the mixture solvent of alcohol hydrogen chloride water. |
