162. Reprocessable Supramolecular Thermoplastic BAB-Type Triblock Copolymer Elastomers with Enhanced Tensile Strength and Toughness via Metal–Ligand Coordination
A new strategy was proposed to enhance tensile strength, toughness, and extensibility of BAB-type reprocessable supramolecular triblock copolymer elastomers (STBCPEs) by simply incorporating 1-vinylimidazole (VI) as a minor comonomer to introduce metal–ligand coordinate bonds of minor contents into the soft matrix. Poly(n-butyl acrylate-co-1-vinylimidazole)-b-poly(isobornyl acrylate)-b-poly(n-b...

Highly Active Organic Lewis Pairs for the Copolymerization of Epoxides with Cyclic Anhydrides: Metal-Free Access to Well-Defined Aliphatic Polyesters
Polyester synthesis from the alternating copolymerization of epoxides with cyclic anhydrides via a metal-free route remains a key challenge. This work reports the development of a highly active organocatalytic route for the copolymerization of a spectrum of epoxides and cyclic anhydrides. Fully alternating polyesters were synthesized by a variety of organic Lewis acid?base pairs including organo...

HCAII-inspired Catalysts for Making Carbon Dioxide-based Copolymers: The Role of Metal-hydroxide Bond
The general characteristics of the active center of the catalysts (including zinc-cobalt(III) double metal cyanide complex [Zn-Co(III) DMCC]) for the copolymerization reaction of carbon dioxide (CO2) with epoxide are summarized. By comparing the active center, catalytic performance of the Zn-Co(III) DMCC (and other catalysts) with HCAII enzyme in the organism for activating CO2 (COS and CS2), we...

Metal-Free Route to Precise Synthesis of Poly(propylene oxide) and Its Blocks with High Activity
The fast and living ring-opening polymerization (ROP) of propylene oxide (PO) by metal-free catalysis is reported. By using triethyl borane (TEB) and organic Lewis bases (LBs, e.g.: phosphazene base, amidine and guanidine) as the catalysts, various alkyl alcohols can effectively initiate the ROP of PO, yielding tailor-made poly(propylene oxide)s (PPOs) with high regioregularity, predictable mole...

[Polym. Chem.] Rare Earth Metal-Mediated Ring-opening Polymerisation of Cyclic Phosphoesters
In this report, simple ytterbocene complex was used for the first time in the ring-opening polymerisation of cyclic phosphoesters. The polymerisation is applicable to both cyclic phosphonates and cyclic phosphates, giving corresponding biodegradable polyphosphoesters with medium to high molar mass and low molecular weight distribution. NMR and MALDI-Tof investigation indicates the polymerisation f...
