| Abstract: | This article presents laboratory synthetic methods of the thermal polymerization of L-aspartic acid. The polymerization is described both with and without the use of a catalyst . The nuclear magnetic resonance and molecular weight of synthetic products are determined. The experimental results showed that polyaspartate was effective in reducing viscosity and was tolerant to Calcium and salt. The studied copolymer meets with the demand of oilfield. |
