Carbon dioxide (CO2) as a sustainable resource instead of toxic reagents has attracted considerable attention in synthesis of chemicals and polymeric materials. Herein, a kind of cyclic oligourea was synthesized via polycondensation of CO2 with 4,7,1

Poly (ethylene glycol)-poly (n-butyl cyanoacrylate) (PEG-PBCA) is a remarkable drug delivery carrier for permeating blood-brain barrier. In this work, a novel high-gravity procedure was reported to intensify Knoevenagel condensation-Michael addition

Covalent organic frameworks (COFs), as a novel class of functional polymers, exhibit versatile applications due to their crystalline porous structures and conjugated skeletons. However, synthesis of COFs with high crystallinity still faces great chal

We draw an analogy between droplet formation in dilute particle and polymer systems. Our arguments are based on finite-size scaling results from studies of a two-dimensional lattice gas to three-dimensional bead-spring polymers. To set the results in

Two conjugated polymers (CPs) Fu-F and Fu-Cl that are soluble in a green solvent anisole were successfully synthesized via direct arylation polycondensation (DArP) using a furan-flanked diketopyrrolopyrrole (DPP) derivative (FDPP-Br) as the C–Br mo

Proposing renewable structures for food packaging applications is necessary for contributing to a low-carbon and sustainable world. Thus, bio-based copolyesters, involving isosorbide (or isomannide), sebacoyl dichloride, and a second rigid acid struc

We develop a simple recursive approach to treat reversible condensation polymerization with cyclization. Based upon a minimum set of balance equations, the law of mass action, Gaussian chain statistics, and the assumption of independent reactions, we

In a preceding work [M. Lang, K. Kumar, A simple and general approach for reversible condensation polymerization with cyclization, Macromolecules 54 (2021) 7021], we have introduced a simple recursive scheme that allows to treat stepwise linear rever

Most commodity polyesters are synthesized via melt polycondensation of dicarboxylic acid and diol using metallic catalysts; however, the resultant metal residues can pose toxic effects on human and environment. Although polyesters can be synthesized

Catalyst-transfer systems have emerged in the condensative chain polymerization of AB-type monomers and stoichiometry-independent polycondensation of AA- and BB-type monomers to synthesize π-conjugated polymers. Although catalyst-transfer polyconden
