A dilatometer was developed for studying the compressibility of polymers in their melting range at pressures to 8500 atm and temperatures to 370°C. Temperature was controlled to ±0.01°C and pressures were maintained and controlled by means of a hydraulic deadweight gauge system. The device was sensitive to volume changes of 1 part in 30,000.
