This work was undertaken to learn more about the complicated role of fillers in reinforcing siloxane polymers and attempt to clarify why silica fillers cause the crosslink density to increase significantly more in siloxane polymers than in hydrocarbo

This 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 duri

This study was undertaken to develop a linear expansion method for identifying transition temperatures in elastomers that would be experimentally easier than dilatometry. It was considered desirable to use isotropic elastomer samples. Anisotropic as
