A process for the manufacture of a block copolymer includes a reaction of a lactide monomers in the presence of a catalyst with a polymer to form the block copolymer having a lactic acid chain, wherein a polymer selected from polypropylene, polyethylene, polysiloxane, polybutylene succinate, polytrimethylene carbonate, polyester, polyether, polystyrene, polyisoprene, polycarbonate, polyalkylenecarbonate, polyvinyl alcohol, polyurethane, or polyacrylate; and wherein the polymer contains n number of OH and/or NH2 group(s), n is an integer greater than or equal to 1 and

and the reaction is performed at a temperature of at least 70° C. The process includes step of quenching of the reaction in order to form the lactic acid chains consisting of 70 or less of the lactide monomers, and the quenching agent is an acid chloride having a formula of Cl—CO—R9, wherein R9 is 1-pentenyl or aminoethyl.
