摘要 |
A method for the preparation of a succinimide copolymer by the catalytic co-polymerization of aspartic acid with a selected polyfunctional monomer in the presence of a cyclic carbonate solvent. Succinimide copolymers of relatively high weight average molecular weight and high purity can be produced in relatively high yields while employing a relatively low catalyst loading.
