## Abstract The hydroxy methyl groups were introduced onto the pristine carbon black surface through the reaction between unsaturated hydrogen atoms of the polycondensed aromatic rings of carbon black and formaldehyde in alkali condition. Using the resultant hydroxy methyl groups on the carbon blac
## 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
