thermal analysis/ high molecular weight poly L-lactide/polyethylene oxide blendsThe miscibility of high molecular weight poly(L-lactide) (PLLA) with high molecular weight poly(ethylene oxide) (PEG) was studied by differential scanning calorimetry. Ail blends containing up to 50 weight% PEO showed ...

According to the method provided by the invention, the high-molecular weight PEG is adopted as a raw material, the use of the reagent with relatively high volatility and toxicity is avoided, the molecular elasticity is improved while the energy consumption is reduced, and the synthesis yield is...
we designed gel electrolytes comprising of 1 wt% of a high molecular weight PEG (Mw = 100 kDa) in diglyme (image shown in Supplementary Fig.19) and investigated them in Li||NCM cells with the same designs as in the previous section, in which the LiBOB salt additive is/is not...
Porous poly(ethylene glycol) terephthalate:poly (butylene terephthalate) (PEGT:PBT) scaffolds with high PEG molecular weight (1000 g/mole) and PEGT content (60%) were fabricated using two different processes-paraffin templating and compression molding-for cartilage engineering applications. This ...
We tested whether coating the viral particle with polyethylene glycol (PEG) could reduce transduction of hepatocytes and hepatotoxicity after systemic (intravenous) administration of oncolytic adenovirus serotype 5 (Ad5). Conjugating Ad5 with high molecular weight 20-kDa PEG but not with 5-kDa PEG ...
Poly(ethylene glycol)s (PEG) of high molecular weights were found to form complexes with α-cyclodextrin (α-CD) in aqueous solutions to give gels in a wide range of concentrations. The time of gelation decreases with increase in α-CD and PEG concentrat
在满足实验用聚合物的相对分子质量超过其自身的聚合物相对分子质量阈值 [MP]的前提下 ,AS PEG或AS PVP混合体系的表面张力 浓度对数 (γ -lgc)曲线呈现拟双平台 (或双拐点 )特征。 2. The threshold molecular weight of polymer is defined as a polymer structure dependent invariant. 定义了聚合物相对分子质...
Biocatalytic "green" synthesis of PEG-based aromatic polyesters: optimization of the substrate and reaction conditions The condensation copolymerization of a variety of linker molecules with polyethylene glycols PEGs of varying molecular weights, catalyzed by lipases under solvent-less conditions is reported...
possible solution to some of these issues (Rupp et al.2008; Fuller et al.1998; Nakagawa et al.2003; Cheng et al.2007; Liao et al.2010); PEO-based gel polymer electrolytes have also been explored, by swelling a high molecular weight PEO matrix with PEG oligomers (Borghini et al.1996)...
