Themolecular massof polymers is not among the key factors that influence gas permeation parameters. In the range of molecular masses, where one can anticipate the strongest effects, poor film forming properties make this question insignificant. Fairly weak effects of molecular mass of polymers onPan...
On the molecular mass distribution of polymers in the branched radical polymerization of polyfunctional monomersdoi:10.1016/0032-3950(91)90012-FA study had been made of MMD changes occurring in the radical polymerization of monoallyl derivatives of endomethylenetetrahydrophthalic acid containing the (meth...
molecular weight- (chemistry) the sum of the relative atomic masses of the constituent atoms of a molecule relative molecular mass mass- the property of a body that causes it to have weight in a gravitational field chemical science,chemistry- the science of matter; the branch of the natural ...
The invention is a method for mass analysis of polymers by mobility measurements of charge reduced ions generated by electrosprays of polymers using solvents having high dielectric constants. Polymer ions formed by electrospray carry a level of charge proportional to their length and hence their mass...
While it's possible to calculate molecular mass for small molecules, it's problematic for polymers and macromolecules because they are so large and may not have a uniform formula throughout their volume. For proteins and polymers, experimental methods may be used to obtain an average molecular ma...
Molecular weight, mass of a molecule of a substance, based on 12 as the atomic weight of carbon-12. It is calculated in practice by summing the atomic weights of the atoms making up the substance’s molecular formula. The molecular weight of a hydrogen m
