AbstractThis study was undertaken to determine the quenching rates necessary to supercool polydimethylsiloxane. A technique was developed that allowed controlled quenching rates up to 52°C/see and a modified DTA apparatus was used to obtain thermograms during the warm‐up cycle. No supercooling was observed for a cooling rate of 1.6°C/sec; 56 supercooling was found for a 9.6°C/sec cooling rate; 65 for 10.6°C/sec and 85 for a 52°C/sec cooling rate. Evidence was also presented showing that the crystals in polydimethylsiloxane consist of two
