Notes:
A study on the anionic polymerization of 2-pyrrolidone in bulk and suspension under isothermal conditions is described. After a discussion about the disadvantages of the bulk process carried out by using N-potassium-2-pyrrolidone as initiator and N-acetyl-ε-caprolactam as activator, a possible alternative way is proposed on the basis of the suspension polymerization initiated by N-potassium-2-pyrrolidone and activated by silicon tetrachloride. The ultraviolet absorption spectra of the polymer samples obtained by the above methods reveal that undesiderable side reactions leading to degradation of the keto amide groups, are almost negligible under the aforementioned conditions.
