The GPC (gel permeation chromatography) curve of the polyethylene sample obtained with 2/TIBA catalyst (50°C, 5 atm, toluene–chlorobenzene) is bimodal indicating that at least two species are active in this system and one is more active than the other. The 2/MAO system (50°C, 5 atm,...
The chemical structure of the diblock copolymer was verified by means of Fourier transform infrared spectroscopy (FT-IR) and 1H-NMR, and the weight average molecular weight (Mw) and polydispersity index (PDI) were measured by gel permeation chromatography (GPC). An mPEG/PLA (20/80) copolymer ...
The structure of the polymer was investigated with FTIR, DSC, GPC, and 13 C-NMR techniques. The polymerization product was composed of polyethylene and syndiotactic polystyrene. No ethylene-styrene copolymer was detected. The composition of the product was dependent on the polymerization conditions. ...
The activities of GPC phosphodiesterases were similar in homogenates and membrane subfractions of renal cortex prepared from control, diuresis and antidiuresis rats. There were no differences in these preparations' ability to hydrolyze phosphorylcholine. In contrast, there was a nearly 50% reduction of...
Similar product suite is obtained by converting concentrated, 15wt% sugar fractions with added 50bar H2in scEtOH. The extensive depolymerization of the sugar polymers and oligomers contained in the sugar fraction is verified by gel permeation chromatography (GPC) and product stability upon catalytic ...
This study deals the modification of bitumen with two new materials, monoethylene glycol based polyboron compound (MEGPC) and diethylene glycol based polyboron compound (DEGPC). These compounds were synthesized chemically and used separately as an additive within the 50/70 penetration grade bitumen....
Polymer molar mass was determined by SEC measurements, performed in THF + 2 wt.% TEA, at 35 °C, using a Polymer Laboratories GPC, equipped with PL-EMD 950 Evaporative Mass Detector (Polymer Laboratories Ltd., Shopshire, UK). 3.2.2. Synthesis of Semi-IPN and IPN PAAm/PDMAEMA Cryogels ...
