ABSTRACT = {In this work, we report a one-pot synthesis of amphiphilic miktoarm cellulose graft copolymers, cellulose
(-graft-oligo(L-lactide))-graft-oligo(N-isopropylacrylamide) (Cell(-g-OLLA)-g-ONIPAM), with dual side chains 
of oligo(L-lactide) and oligo(N-isopropylacrylamide) using 2-bromoisobutyl bromide functionalized cellulose 
(Cell(-OH)-Br) as the macroinitiator, by simultaneously conducting ring-opening polymerization and atom 
transfer radical polymerization using Cu/CuBr/PMDETA/Sn(Oct)<sub>2</sub>
 as the catalytic system. The chemical 
structures and thermal properties of Cell(-g-OLLA)-g-ONIPAMs were characterized with <sup>1</sup>
H and <sup>13</sup>C nuclear 
magnetic resonance spectroscopy, differential scanning calorimetry and thermal gravimetric analysis. Cell
(-g-OLLA)-g-ONIPAM could self-assemble into micelles in the aqueous solution as confi rmed by 
environmental scanning electron microscopy and dynamic light scattering analyses. The micellar aggregates 
showed a temperature-responsive property and the sizes of micelles were infl uenced by the ratio of 
temperature-responsive ONIPAM side chains. The miktoarm graft copolymers have potential applications as 
biomedical or intelligent materials.},
