By use of carbon black containing quaternary ammonium carboxylate (COO-N+Rd groups as catalyst, the anionic ring opening polymerization of P-propiolactone (PL) was carried out a t 5OOC. Although carbon black itself was unable to initiate the polymerization of PL, carbon black containing COO-N+R,j gr
