Poly(trimethylene monothiocarbonate) from the Alternating Copolymerization of COS and Oxetane: A Semicrystalline Copolymer
ABSTRACT: A semicrystalline poly(trimethylene monothiocarbonate) (PTMMTC) has been synthesized via the selective and alternating copolymerization of carbonyl sulfide and oxetane. This reaction was catalyzed by (salen)CrCl accompanied by organic bases over a wide range of temperatures from 40 to 130 °C. PTMMTC is shown to exhibit similar crystallization behavior to high-de...

Poly(monothiocarbonate)s from the Alternating and Regioselective Copolymerization of Carbonyl Sulfide with Epoxides
CONSPECTUS: Carbonyl sulfide (COS) is an air pollutant that causes acid rain, ozonosphere damage, and carbon dioxide (CO2) generation. It is a heterocumulene and structural analogue of CO2. Relevant to organic synthesis, it is a source of C=O or C=S groups and thus an ideal one-carbon (C1) building block for synthesizing sulfur-containing polymers through the simila...

Well-defined high refractive index poly(monothiocarbonate) with tunable Abbe''s numbers and glass-transition temperatures via terpolymerization
The synthesis of thermoplastics with high refractive index (n) and high Abbe’s number (Vd) is rarely reported. This work describes well-controlled synthesis of a soluble poly(monothiocarbonate) with high n and Vd values by using carbonyl sulfide (COS) as sulfur resource. The alternating COS/cyclohexene oxide (CHO)/propylene oxide (PO) terpolymerization was well performed by using...

Highly Efficient One-Pot Synthesis of COS-Based Block Copolymers by Using Organic Lewis Pairs
关键字:metal-free Lewis pairs,poly(monothiocarbonate) block copolymer,carbonyl sulfide,immortal polymerization
A one-pot synthesis of block copolymer with regioregular poly(monothiocarbonate) block is described via metal-free catalysis. Lewis bases such as guanidine, quaternary onium salts, and Lewis acid triethyl borane (TEB) were equivalently combined and used as the catalysts. By using polyethylene glycol (PEG) as the macromolecular chain transfer agent (CTA), narrow polydispersity block copolym...
