| Abstract: | Diblock copolymer poly(n-butyl methacrylate)-block-poly(10-hydroxydecanoate)(PnBA-b-PHD) was prepared by one pot strategy via combination of enzymatic polymerization of 10-hydroxydecanoate(HD) and atom transfer radical polymerization(ATRP) of n-butyl methacrylate(nBA). The obtained copolymer was characterized by 1H NMR, FTIR and gel permeation chromatography(GPC). The solution properties of diblock copolymer into water in dry state were examined by atom force microscopy(AFM), in which well-dispersed spherical micellar structure in mono-modal pattern was clearly observed with a size value around 135 nm. Whereas the hydrodynamic diameter of the aggregates surrounded in tetrahydrofuran(THF) was determined by dynamic light scattering(DLS) instrument. |
| Keywords: | One-pot Enzymatic self condensation polymerization(eSCP) Atom transfer radieal polymerization(ATRP) Diblock copolymer |
