Facile Synthesis and Topological Transformation of Multicomponent Miktoarm Star Copolymers
Multicomponent miktoarm stars (MMSs) comprising at least three kinds of chemically different arm segments are extremely important due to their great potential as multiphase materials to elucidate composition/ topology-dependent properties and applications. At present, a “core first” route gives ABC stars, “coupling onto” and combinatorial methods afford ABC and ABCD stars, and modular and it...

Synthesis and self-assembly of a dual-responsive monocleavable ABCD star quaterpolymer
ABCD star quaterpolymers acquired by precision synthesis may provide us with insights into self-assembly due to their fused architectures of di?erent arm segments and a central core. Considering the crucial role of external stimuli in smart materials, the aims of this study are the facile synthesis of a pH/redox-responsive 4-arm miktoarm star and the study of its stimuli-dependent aggregation be...

Epoxy-functionalized star-shaped polymers as novel tougheners for epoxy resin
A novel epoxy resin toughener based on star-shaped copolymer of butyl acrylate (BA) and glycidyl methacrylate (GMA) [poly (BA-co-GMA)] with low viscosity was developed. The star polymers were synthesized by initiators for continuous activator regeneration atom transfer radical polymerization (ICAR ATRP) using tri, tetra and hexa-functional initiators. The branching parameters of star poly (BA-co...

Synthesis and properties of an acid-labile dual-sensitive ABCD star quaterpolymer
Synthesis of multicomponent miktoarm stars (MMS) has attracted much attention due to their intriguing morphologies and multipurpose applications. Thus far, the examples of stimuli-cleavable MMS are very scarce. This study aims at modular synthesis of the first example of an acid-labile ABCD star quaterpolymer and exploring its potential in smart drug delivery systems. An alkyne-core-functionaliz...

Self-Assembly of Large Multimolecular Micelles from Hyperbranched Star Copolymers
This work focused on the synthesis and aqueous self-assembly of a series of novel hyperbranched star copolymers with a hyperbranched poly[3-ethyl-3-(hydroxymethyl)oxetane] (HBPO) core and many linear poly[2-(dimethylamino)ethyl methacrylate] (PDMAEMA) arms. The copolymers can synchronously form unimolecular micelles (around 10 nm) and large multimolecular micelles (around 100 nm) in water a...
