Abstract

The PASP (polyaspart ic acid)is synthesized by means of pyrocondensation polymerizatio n, using maleamic acid as a monomer.The inf rared spectrogram and molecular weig ht of synthetic products are determined.The biodeg radability, scale inhibition and relation of it w ith molecular are invest ig ated.The results show that PASP is a biodeg radable and excellent green scale inhibito r.The molecular weig ht range is 2 000 ~ 3 000.
