Claim:
1. A system for measuring glass transition temperature of a polymer, comprising: a cell having a closed bottom and a peripheral wall extending from the bottom; a sample holder disposed on the cell bottom for retaining a polymer sample thereon, the sample holder including a first supporting pin and a second supporting pin, the second supporting pin being spaced apart from the first supporting pin; a loading probe adjustable between at least a raised and a lowered position for selectively contacting the polymer sample; a temperature probe extending into the cell for measuring a temperature of the polymer sample; a heater in communication with the cell for heating the cell; a temperature sensor in communication with the cell for measuring a temperature within the cell; a source of pressure in communication with the cell; a source of gas in communication with the cell; and a data acquisition system operably connected to the loading probe, the temperature probe and the source of pressure; whereby the first and second supporting pins and the loading probe provide a three-point flexural bending assembly for measuring bending of the polymer sample under varied conditions of temperature and pressure.
