New discoveries in chemical research and development in 2021.In classical electrochemical theory, both the electron transfer rate and the adsorption of reactants at the electrode control the electrochemical reaction. In an article, author is Liu, Shuning, once mentioned the application of 556-50-3, Name is 2-(2-Aminoacetamido)acetic acid, molecular formula is C4H8N2O3, molecular weight is 132.1179, MDL number is MFCD00008130, category is pyrrolines. Now introduce a scientific discovery about this category, Application In Synthesis of 2-(2-Aminoacetamido)acetic acid.
Design and properties of polyarylene ether nitrile copolymers with improved elongation at break
Polyarylene ether nitrile (PEN) based on biphenol exhibits a high glass transition temperature of 216 degrees C, a high tensile strength of 110 MPa, and low elongation at break of approximately 4%. A series of PEN random copolymers with improved elongation at break were synthesized using various bisphenol compounds and 2,6-dichlorobenzonitrile (DCBN). The resulting PEN random copolymers exhibited a high glass transition temperature and thermal stability up to 513 degrees C in a nitrogen atmosphere. PEN copolymers were amorphous and could easily be cast into transparent films with a tensile strength of 97.93-117.88 MPa and tensile modulus of 2187.98-2558.44 MPa. Most importantly, elongation at break of these PEN copolymers was higher than 13%. PEN copolymer films had a dielectric constant of 3.77-3.89 at 1 kHz and extremely low dielectric loss (<0.02). At the same time, the breakdown strength of PEN was in the range of 137.92-198.19 kV/mm and energy storage density was in the range of 0.32-0.68 J/cm(3). Excellent mechanical, thermal, and dielectric properties of PEN make it possible to use them as high-temperature resistant dielectrics to act on high-temperature resistant insulated cables. The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules.
