Investigation of the Temperature of a Relaxation (Above the Glass Transition Temperature) in Polystyrene by Torsional Braid Analysis.

摘要

Investigation of the T sub ll (> T sub g) transition in amorphous polystyrene by the technique of torsional braid analysis is reviewed. For the most part, the relaxation behaves like the glass transition (T sub g) in its dependence on molecular weight, on average molecular weight in binary polystyrene blends, and on composition in a compatible plasticized system.
