Abstract

In a previous paper we have concluded that polymer incompatibility in aqueous two-polymer systems are due to an unfavourable segment-segment interaction between the two polymers. In order to further study the molecular interactions leading to phase separation, the temperature dependence for the system poly(ethylene glycol)-dextran-water has been investigated.
