Thermal polymerization of a salt of aspartic acid affords polyaspartate directly without hydrolyzing polysuccinimide. Copolymerization of a salt of aspartic acid with aspartic acid itself affords a copolymer of succinimide and aspartate which may be readily derivatized to produce a sulfonated, phosphonated or hydrophobized polymer.
La polymérisation thermique d'un sel d'acide aspartique permet d'obtenir directement un polyaspartate, sans hydrolysation de polysuccinimide. La copolymérisation d'un sel d'acide aspartique et dudit acide aspartique permet d'obtenir un copolymère de succinimide et d'aspartate pouvant produire facilement, par dérivatisation, un polymère sulfoné, un polymère phosphonaté ou un polymère rendu hydrophobe.
