Polymer Characterization: Polymer Molecular Weight Determination
Polymers are large molecules consisting of a large number of small component molecules chemically linked together. They are made from constituent monomers through polymerization process. Polymers are unique materials in that they consist of a statistical distribution of chains of varying lengths, and each chain consists of monomer residues which affect its properties hence they require several ...
متن کاملOsmotic Pressure, Molecular Weight, and Stability of Serum Albumin”
Because of the discrepancies at the time this investigation was begun in the estimates of t’he molecular weight of serum albumin, as made by Siirensen (1) (45,000) and hdair (2) (62,000) by means of osmotic pressure experiments, and by Svedberg and Sjiigren (4) (67,500) from ultracentrifugal measurements, the osmotic pressure of this protein was reinvest’igated under more suitable experimental ...

متن کاملSelf-assembled polymer membrane capsules inflated by osmotic pressure.
We fabricate and characterize capsules that are composite membranes, made of a polymer network stabilized by adsorption to colloids and inflated by osmotic pressure from internal free polyelectrolyte; here, poly-l-lysine forms the network and inflates the capsules. To assess these capsules' properties and structure, we deform capsules using microcantilevers and use finite element modeling to de...
متن کاملOsmotic Pressure of Solutions Containing Flexible Poly - mers Subject to an Annealed Molecular Weight Distribu - tion
– The osmotic pressure P in equilibrium polymers (EP) in good solvent is investigated by means of a three dimensional off-lattice Monte Carlo simulation. Our results compare well with real space renormalisation group theory and the osmotic compressibility K ∝ φdφ/dP from recent light scattering study of systems of long worm-like micelles. We confirm the scaling predictions for EP based on tradi...
