متن کاملDetermination of the chemical composition distribution of copolymers of styrene and butadiene by gradient polymer elution chromatography
In order to determine the chemical composition distribution (CCD) of styrene-butadiene copolymers, gradient polymer elution chromatography has been performed. The separation is mainly based on differences in solubility among the copolymer molecules with different chemical composition. The solubility of a copolymer is dependent on the following parameters: temperature, type of solvent/non-solven...
متن کاملDiffusion of residual monomer in polymer resins.
A simplified mathematical model which made use of Fick's laws of diffusion written in spherical coordinates was developed to describe the rate of diffusion of residual monomers from polymer resins. The properties of the monomer-polymer system which influenced the amount of monomer remaining in the polymer as a function of time were the diffusivity and solubility of the monomer in the polymer, a...
متن کاملElectrogenerated chemiluminescence of pure polymer films and polymer blends.
We recently reported the discovery of soliton-like electrogenerated chemiluminescence (ECL) waves from pure conjugated polymer films and gold-nanoparticles-doped polymer films. In addition to a more detailed study of these polymer systems by changing the film thickness and the distribution of local leaks, we also apply the ECL wave phenomenon to polymer blends of conjugated and nonconjugated po...
متن کاملMonomer-polymer equilibria in the axon: direct measurement of tubulin and actin as polymer and monomer in axoplasm
The monomer-polymer equilibria for tubulin and actin were analyzed for the cytoskeleton of the squid giant axon. Two methods were evaluated for measuring the concentrations of monomer, soluble (equilibrium) polymer, and stable polymer in extruded axoplasm. One method, the Kinetic Equilibration Paradigm ( KEP ), employs the basic principles of diffusion to distinguish freely diffusible monomer f...
