关键字：controlled ring-opening polymerization (CROP); reversible addition-fragmentation chain transfer (RAFT); "living"/controllable polymerization; star block copolymer;
Reversible addition-fragmentation chain transfer (RAFT) polymerization is a more robust and versatile approach than other living free radical polymerization methods for synthesis of well-defined homo-, gradient, block, star-shaped and more complex structural polymers, like micro(nano)gels and polymer brushes. Thus the resultant polymers with thiocarbonylthio-terminated groups are readily tailored ...

【Journal of Materials Chemistry A】A Si-doped flexible self-supporting comb-like polyethylene glycol copolymer (si-peg) film as a polymer electrolyte for an all solid-state lithiumion battery,
Abstract:
Herein, a self-supporting comb-like Si-PEG copolymer with flexible Si-O-C bonds in the main chain and pending short PEG chains as the side chain was synthesized to improve the low temperature performance and overcome the quandary between good mechanical and electrochemical properties of the polymer electrolyte in lithium-ion batteries. The tensile strength of Si-PEG polymer electrol...

A series of water-soluble and cationic methoxy poly(ethylene glycol)-b-poly(g-amino-3-caprolactone) (mPEG-b-PACL) has been synthesized via ring opening polymerization of g-(carbamic acid benzyl ester)-3-caprolactone (gCAB3CL) using mPEG as a macroinitiator and Sn(Oct)2 as a catalyst, and subsequent hydrolysis of the Cbz protecting groups under acidic conditions. The well-defined structure
of copo...

In this paper, aliphatic polyesters functionalized with pendant carboxylic groups were synthesized via several steps. Firstly, substituted cyclic ketone, 2-(benzyloxycarbonyl methyl)cyclopentanone (BCP) was prepared through the reaction of enamine with benzyl-2-bromoacetate, and subsequently converted into the relevant functionalized δ-valerolactone derivative, 5-(benzyloxy carbonylmethyl)-&...

A facile hard-templating route has been successfully developed to fabricate uniform hollow mesoporous silica spheres and ellipsoids by using hematite as hard template. The outer diameter of the spherical mesoporous silica particles can be well adjusted in a sub-micrometric range (typically around 100–200nm) by selecting suitable hematite particles as core templates. The thickness of the meso...

The electron-withdrawing groups (EWGs) in the electrophilic alkenes employed in the Michael addition reaction are almost only CO2R, CN, COR, NO2, and SO2Ph. Although amides (CONR1R2) are also typical electron-withdrawing groups and are of great importance in organic synthesis, they are scarcely employed as the EWGs of the electrophilic alkenes in the Michael addition reaction. In this work, the Mi...

Poly(ethylene oxide) containing azo groups (pre-PEO) was prepared by reacting azoisobutyronitrile (AIBN) with poly(ethylene oxide) (PEG). The molecular weight of pre-PEO was depended on the reaction time, the ration of PEG to AIBN and the molecular weight of PEG. Pre-PEO decomposed in the presence of butylacrylate (BA) monomer to from poly(ethylene oxide-block-butylacrylate) copolymers (PEO-b-PBA)...
