Sentence examples for molecular weight models from inspiring English sources
The polymers display optical activity in solution much higher than that afforded by the corresponding low molecular weight models, representative of the monomeric repeating unit, purposely synthesized.
At the same time, significant variability, of the order of 1000% of the mean, in the stress strain relationships and the Young's modulus predictions was observed, especially for low molecular weight models.
The difference between the photoinitiation activity of the polymeric system and the low molecular weight models is explained in terms of the effect of the polymer chain on the reactivity of the amino radicals.
Since δ of the high molecular weight models computed from (Eiu−El) agree with experiment better than those from (Eip−El), it implies that δ obtained from indirect measurements correspond to a hypothetical vaporization process where the conformations of polymer coils do not undergo significant changes.
The second method uses a low molecular weight model monomer (MTm) that reproduces the chemical structure of the macromonomer.
The copolymers exhibit polymerization rates and quantum yields similar to those of the low molecular weight model compounds.
The 3D matrices were evaluated for in vitro release using two different molecular weight model compounds, bovine serum albumin (66 kDa) and FITC Inulin (3.9 kDa).
In the final models, the aromatic ester torsion angles are distributed about means that are close to those observed in low molecular weight model compounds.
Low molecular weight model trisegmented polyurethanes based on monofunctional polyols, or 'monols', with water-extended toluene diisocyanate (TDI) based hard segments (HS) are investigated.
These values were not dependent on the overall structure or molecular weight of the polymer backbone and were nearly identical to those determined for several lower molecular weight model compounds.
A novel optically active monomer containing a photochromic chromophore, such as trans- S -4- 2-methacryloyloxypropanoyloxy)azobenzene and itrans- S -4- 2-methacryloyloxypropanoyloxyns-(S)-4-(2-pivaloyloxypropanoyloxy)azobenzene were prepared.
