Formation of mesoglobules from phase separation in dilute polymer solutions: a study in experiment, theory, and applications

Dawson, K.A.; Gorelov, A.V.; Timoshenko, E.G.; … - In: Physica A: Statistical Mechanics and its Applications 244 (1997) 1, pp. 68-80

The appearance of spherical particles resulting from heating beyond the phase separation temperature in dilute solutions of poly(N-isopropylacrylamide) has been observed by dynamic light scattering (DLS). They have a relatively narrow size distribution. The size of particles increases with...

Monte-Carlo simulation for the kinetics of collapse and phase separation in homopolymer solutions

Byrne, A.; Timoshenko, E.G.; Dawson, K.A. - In: Physica A: Statistical Mechanics and its Applications 243 (1997) 1, pp. 14-24

after a quench to the poor solvent region. Each chain may collapse individually as well as aggregate with others, and the … rather long compared to the collapse time of an isolated chain even for large quenches considered here. Our findings agree …
