Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Dielectric spectroscopy (DS) and dynamic light scattering (DLS) are employed to study the dynamics of poly(n-lauryl methacrylate) (PnLMA) (M(w) 1.1 x 10(5)) at temperatures below and above the glass transition temperature T-g (T-g approximate to 225 K). T

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Correlation functions measured in dynamic light scattering on polymer solutions often contain a strong sharp decay which obscures and renders difficult a reliable analysis of other decay processes. We demonstrate that this problem can be circumvented by p

Multiple relaxations of concentration fluctuations in entangled polymer solutions

Ingår i: MACROMOLECULES. - : AMER CHEMICAL SOC. - 0024-9297. ; 31:6, s. 1889-1897
-
Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- We have investigated by dynamic light scattering the dynamics of semidilute polymer solutions in a good solvent, specifically polystyrene in benzene. We have shown that, using state-of-the-art instrumentation and data analysis techniques, it is possible t

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- We have investigated relaxations in a semidilute solution of a high molecular weight polystyrene in the vicinity of Theta conditions, using three different techniques: dynamic light scattering, relaxation of flow after cessation of shear recorded through
