| Abstract: | The polyaspartic acid is synthesized by means of pyrocondensation polymerization ,using aspartic acid as a monomer.The effect of temperature and time on yield is studied. The scale inhibition performences of polyaspartic acid in different concentration are studied.The experimental results show that polyaspartic acid has excellent scale inhibition and dispersion performence and is a enviromentally friendly water stabilizing agent. |
