Abstract
Selon l'invention, on produit un polysuccinimide par polymérisation thermique d'un précurseur ou d'un mélange de réactifs comprenant un composé insaturé, dans un réacteur à plaques (14), à des températures suffisantes pour amorcer la polymérisation et former un solide cassant. Le polysuccinimide ainsi obtenu peut être transformé par hydrolyse en acide polyaspartique ou en un sel d'acide polyaspartique, si désiré. Le précurseur susmentionné peut être un monomère ou un mélange de réactifs formant des intermédiaires polymérisables.
