The physico-chemical properties
of poly(ethylene) glycol solutions in water have been studied with use of
pressure perturbation calorimetry. The three PEGs of average molecular mass
(Mr) 6000, 10000,
20000 were used. The concentration of polymers was changed in the range 0–30%
mass per volume (w/v%).
On the basic of VP-DSC measurements with use of PPC technique the dependencies
of thermal expansion coefficient (α) and excess specific heat capacity
(Cp,exc) on temperature
were determinated for PEG–water solutions.
