Intermolecular Hydrogen Bonding of Poly(Imino Imino Ketone Ketone)
关键字：hydrogen bonding, molecular simulation, poly(imino imino ketone ketone)
Molecular dynamics calculations were made of the distance from the hydrogen atom of the imino group to the distance of the oxygen atom of the carbonyl group of poly(imino imino ketone ketone) (PIIKK). The results showed that theoretically there was hydrogen bond formation between the hydroxyl group and the carbonyl group of PIIKK. The existence of the hydrogen bonding between the polymer chains ...

Facile synthesis of soluble aromatic poly(amide amine)s via C–N coupling reaction: Characterization, thermal, and optical properties
关键字：aromatic poly(amide amine)s; high-performance
Aromatic poly(amide amine)s (APAAs), as novel highperformance polymers, have been obtained by the condensation polymerization of N,N’-bis(4-bromobenzoyl)-p-phenylenediamine with two different primary aromatic diamines via palladiumcatalyzed aryl amination reaction. The structures of the polymers are characterized by means of FTIR, 1H NMR spectroscopy, and elemental analysis, the results show a ...

Poly(vinylphosphonate)s with Widely Tuneable LCST: A Promising Alternative to Conventional Thermoresponsive Polymers
关键字：Group transfer polymerization, cloud point, poly(vinylphosphonate)s, rare earth metals
Novel statistic copolymers of dialkyl vinylphosphonates have been synthesizedvia rare earth metal-mediated group transfer polymerization using easily accessible tris(cyclopentadienyl) ytterbium. The copolymerization parameters have been determined by activity measurements showing the formation of almost perfectly random copolymers (r1, r2 ~ 1). Thus, the polymerization rate of vinylphosphonate GTP...
