## Abstract By use of carbon black that contained alkali metal carboxylate (ο£ΏCOOM; Mο£ΎLi, Na, K, Rb, or Cs) group as catalyst the anionic polymerization of Ξ²βpropiolactone (PL) was carried out at 50Β°C and the grafting of polyester onto the carbon black surface was investigated. Carbon black that con
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
