The use of Raman spectroscopy for real-time gas monitoring has the advantages corresponding speed, high sensitivity and low cost. However, due to overlap each peak position, the...
Silicone rubber foam is recognized for its heat resistance and lightweight properties, making it suitable a variety of applications. However, the relationship between formulation, crosslinking network structure, rheological properties foaming behavior not thoroughly understood. In this work, contents crosslinked chains, dangling chains free were characterized by low-field nuclear magnetic resonance (LF-NMR), which revealed transformation into with increasing content agent. Additionally,...
Multiblock copolymers poly(l-lactic acid)-block-poly(butylene succinate-co-butylene adipate)s (abbr. P(LLA-mb-BSA)s) are synthesized via a polycondensation/chain extension/coupling method using binary chain extenders. A acid) (PLLA) prepolymer direct melt polycondensation of l-lactic acid is rapidly extended with bis (2-oxazoline) to form hydroxyl terminated dimer, and the dimer then extended/coupled poly(butylene adipate) (PBSA) by diisocyanate. The microstructure characterized GPC, 1H NMR...
Abstract Polyketone (PK) has attracted wide attention owing to its direct utilization of carbon monoxide, excellent properties, and photodegradation performance. However, the commercialized PK is produced using Pd‐based catalysts, which accounts for largest part production cost. Herein, [Ni(2‐tol)(PPh 3 )(N,O)] used as main catalyst high productivity good tolerance CO. Effects cocatalyst (Ni(COD) 2 ), aging method in CO atmosphere, polarity solvent are investigated. When Ni(COD) employed...
In this paper, cellulose chitosan composite aerogels were prepared through sol–gel and freeze-drying processes. The porous morphology of the was controlled by adjusting concentration. Within a certain range, as concentration increases, pore diameter aerogel becomes smaller structure denser. cellulose–chitosan can successfully separate oil–water mixture without asphalt showed stable filtration performance. speed is basically unchanged after slight decrease be maintained at about 90% initial...
Polyketone (PK) is a promising material because of its superior qualities as an engineering plastic and the direct use CO. It typically produced using slurry polymerization techniques, which cause reactor fouling low bulk density product. Here, solution CO/ethene/propene with high-molecular-weight products (240.3 kDa) high catalytic activity (36.1 kg PK·g–1 Pd·h–1) was achieved utilizing mixture hexafluoroisopropanol (HFIP) methanol. Both Mw are order magnitude higher than those reported in...
The loading of homogeneous catalysts with support can dramatically improve their performance in olefin polymerization. However, the challenge lies development supported well-defined pore structures and good compatibility to achieve high catalytic activity product performance. Herein, we report use an emergent class porous material-covalent organic framework material (COF) as a carrier metallocene catalyst-Cp2 ZrCl2 for ethylene COF-supported catalyst demonstrates higher 31.1×106 g mol-1 h-1...
Polypropylene reactor alloys with distinct structures were synthesized, and machine learning models developed to reveal the relationship between process–structure–properties optimize process conditions.
In this work, nylon 6 (PA6) and cationic dyeable polyester (CDP) modified with benzenesulfonate groups were reactively blended in a twin-screw extruder. The well-mixed CDP/PA6 blends re-molten statically kept for various amounts of time. morphology evolution caused by phase separation was observed scanning electron microscope (SEM) an atomic force microscopy-infrared (AFM-IR) technique. the absence shear force, homogeneously mixed found to separate rapidly into two phases because poor...
Abstract The uniformity of copolymer composition has a great influence on its properties; however, it is very difficult to control. Especially in the laboratory research multi‐component gas‐phase copolymerization olefins, polymerization usually conducted batch reactor, and resulting copolymers often distributed widely. samples such are fact not representative. Detection control atmospheric reactor during olefin significance for composition. In this work, method based three flow meters series...
Covalent organic framework (COF) particles with hydroxy groups and well-defined micropores have been synthesized used as novel carriers to load a metallocene catalyst—Cp2ZrCl2. The resulting supported catalyst, which had high specific surface area, demonstrated higher catalytic activity, better thermal tolerance, unique nanoconfinment effect during ethylene polymerization, producing polyethylene molecular weight, increased crystallinity, highly improved mechanical performance. More...
Abstract This study addresses the challenges of time‐delay and low accuracy in online gas‐phase composition monitoring during olefin copolymerization processes. Three flowmeters based on different mechanisms are installed series to measure real‐time exhaust gas flow rate from reactor. For same flow, three display readings, which vary with properties mixture. Consequently, mixed can be determined by analyzing reading flowmeters. Fitting equations machine learning models, namely decision...
