| 摘 要： | The hyperbranched aliphatic polyester P(e-CL) was synthesized by means of Novozyme435-catalyzed ring-opening polymerization (ROP) of BHB (2, 2-bis(hydroxymethyl) butyric acid). The chains ended with hydroxyl of P(e-CL) were modified by the esterification of a-bromopropionyl bromide to obtain hyperbranched difunctional macroinitiator, which was used in the ATRP of St. CuCI/HMTETA was used as the catalyst system in the reaction of ATRP to acquire the hyperbranched copolymers polystyrene-block-poly(2,2-bis(hydroxymethyl) butyric acid). The copoly-mer was confirmed by NMR and GPC.
