Polyesteracetals via TBD Catalyzed Ring‐Opening Polymerization

Macromolecular Rapid Communications, EarlyView.
The ring‐opening polymerization (ROP) of a cyclic hemiacetal ester catalyzed by 1,5,7‐triazabicyclo[4.4.0]dec‐5‐ene (TBD) yields statistical copolymers containing esteracetal as well as ester repeating units. Their ratio can be tailored through adjustment of the ROP conditions.

A new method for estimating the content of vinyl acetate in ethylene-vinyl acetate copolymer

IEEE Transactions on Dielectrics and Electrical Insulation, 2016
A new method for estimating the content of vinyl acetate (VA) in ethylene-vinyl acetate copolymer (EVA) is proposed. It is a kind of optical absorption spectroscopy in a frequency range from 0.5 to 21.0 THz. Comparison of absorption spectra among sheets of EVA with differing contents of VA from 12 to 60% by weight and a sheet of low-density ...

Solubility of acetylene in vinyl acetate and in a mixture of vinyl acetate and acetic acid

Journal of Chemical & Engineering Data, 1992
Solubilities of acetylene in vinyl acetate and its mixture with acetic acid (1:1 molar ratio) were measured at temperatures from -15 to 0 o C and at pressures from 20 to 100 kPa. Solubilities are characterized by mole fractions of acetylene and by Henry's constants.

ChemInform Abstract: CONFORMATIONS OF VINYL FORMATE AND VINYL ACETATE

Chemischer Informationsdienst, 1976
Ab initio molecular orbital theory has been used to deduce the preferred gas-phase conformations of vinyl formate and vinyl acetate. In addition, experimental dipole moments (1030μ/Cm) and molar Kerr constants (1027mK/m5 V-2 mol-1) at 25 C are reported for both molecules as solutes in carbon tetrachloride: vinyl formate (5.07, + 48.1) and vinyl ...

One-Step Preparation of Long-Term Stable and Flexible CsPbBr3 Perovskite Quantum Dots/Ethylene Vinyl Acetate Copolymer Composite Films for White Light-Emitting Diodes.

ACS Applied Materials and Interfaces, 2018
CsPbBr3 perovskite quantum dots (PQDs)/ethylene vinyl acetate (EVA) composite films were prepared via a one-step method; on the basis of this, both supersaturated recrystallization of CsPbBr3 PQDs and dissolution of EVA were realized in toluene.

Metabolism and pharmacokinetics of vinyl acetate

Archives of Toxicology, 1985
The hydrolysis of vinyl acetate (formation of acetic acid) has been studied in vitro with rat liver and lung microsomes, rat and human plasma and purified esterases (such as acetylcholine esterase, butyrylcholine esterase, carboxyl esterase). Characterization of the kinetic parameters revealed that rat liver microsomes and purified carboxyl esterase ...
