[Polym. Chem.] Topological Analysis and Intramolecular Cyclic Feature Evaluation of Highly Branched Polymers Derived from Am+Bn Step-Growth Polymerization
In this contribution, we investigated the evaluation strategy for intramolecular cyclic features of polymers derived from Am + Bn (m ≥ 2 and n ≥ 2) step-growth polymerization from a topological analysis perspective. The general quantitative relationship between the structural units and the cyclic structures was presented
regardless of the terminal groups of polymers. Further, two strat...

[Polym. Chem.] Miktoarm star polymers with poly(N-isopropylacrylamide) or poly(oligo(ethylene glycol) methacrylate) as building blocks: synthesis and comparison of thermally-responsive behaviors
We synthesized two thermally-responsive miktoarm star polymers in which poly(Nisopropylacrylamide) (PNIPAM) or poly(oligo(ethylene glycol) methacrylate) (POEGMA) served as the thermosensitive building blocks.The obtained miktoarm star polymers were comprised of a b-CD core, a PEG arm and about six PNIPAM or POEGMA arms. Furthermore, the thermally-responsive behaviors of the mik...

[Polymer Chemistry] Three new conjugated polymers based on benzo[2,1-b:3,4-b′]dithiophene: synthesis, characterization, photoinduced charge transfer and theoretical calculation studies
Three new conjugated polymers have been designed and synthesized via the alternate copolymerization of the electron-donating monomer benzodithiophene (BDT) and three different electron-accepting monomers: 5,8-dibromoquinoxaline, 5,8-dibromo-2,3-diphenylquinoxaline, 10,13-dibromodibenzo[a,c]phenazine. The synthesized polymers show good solubility in co...

[J. Phys. Chem. B] Terminal Index: a New Way for Precise Description of Topologic Structure of Highly Branched Polymers Derived from A2+B3 Step-wise Polymerization
Terminal index (TI) was presented as a new characteristic parameter for quantitative description of branched and cyclic topology of highly branched soluble polymers derived from A2 + B3 stepwise polymerization. TI is defined as the ratio of terminal units of an A2 + B3 type highly branched polymer to those in its perfect hyperbranched counterpart. TI is concisely represent...

Miktoarm star polymers with poly(N-isopropylacrylamide) or poly(oligo(ethylene glycol) methacrylate) as building blocks: synthesis and comparison of thermally-responsive behaviors
We synthesized two thermally-responsive miktoarm star polymers in which poly(Nisopropylacrylamide) (PNIPAM) or poly(oligo(ethylene glycol) methacrylate) (POEGMA) served as the thermosensitive building blocks. Firstly, linear methoxypolyethylene glycol (PEG) with β-cyclodextrin (β-CD) bearing about six chlorines as a terminal (PEG-CD-Clx, x z 6) was synthesized. Then, the thermally-respon...

21. Relationship between Frank elastic-constant anisotropies measured from lamellar and of molecular directors of disclinations in main-chain liquid crystalline polymers
The transmission electron microscope technique enables direct visualization of disclination core structure of main chain liquid crystalline polymers. Generally, the lamellar structure, that is a function of type of polymer and molecular length, and of which the thickness is 10-200 nm, can be observed. In terms of distortions in the director field produced by a disclination, the elastic anisot...

[Macromol. Rapid Commun.] Synthesis of Seven-Arm Poly(vinyl pyrrolidone) Star Polymers with Lysozyme Core Prepared by MADIX/RAFT Polymerization
A poly(vinyl pyrrolidone) (PVP) seven-arms star polymer with lysozyme core was synthesized by conjugating linear N-succinimidyl ester terminated PVP polymer to lysozyme. Reactive PVP polymers were synthesized using a MADIX/RAFT agent functionalized with N-succinimidyl ester. The polymerization of N-vinyl pyrrolidone proceeded in a living fashion up to more than 90% conversion reaching molecular we...
