Shou-Kuo Man, Xiao Wang, Jin-Wen Zheng, et al. Effect of Butyl
Polymerization-induced self-assembly (PISA) is an efficient and versatile method to afford polymeric nano-objects with polymorphic morphologies. Compared to dispersion PISA syntheses based on soluble monomers
the vast majority of emulsion PISA formulations using insoluble monomers leads to kinetically-trapped spheres. Herein
we present aqueous emulsion PISA formulations generating worms and vesicles besides spheres. Two monomers with different butyl groups
n
-butyl (
n
BHMA) and
tert
-butyl (
t
BHMA)
α
-hydroxymethyl acrylate
and thus possessing different water solubilities were synthesized
via
Baylis-Hillman reaction. Photoinitiated aqueous emulsion polymerizations of
n
BHMA and
t
BHMA employing poly(ethylene glycol) macromolecular chain transfer agents (macro-CTAs
PEG
45
-CTA
and PEG
113
-CTA) at 40 °C were systematically investigated to evaluate the effect of monomer structure and solubility on the morphology of the generated block copolymer nano-objects. Higher order morphologies including worms and vesicles were readily accessed for
t
BHMA
which has a higher water solubility than that of
n
BHMA. This study proves that plasticization of the core-forming block by water plays a key role in enhancing chain mobility required for morphological transition in emulsion PISA.
