โฆ Synopsis
The kinetics of polycondensation of hydroxyfunctional polydimethylsiloxane has been studied with a simple new inexpensive piece of equipment, i.e., the vibrating needle curemeter. The order of reaction with respect to crosslinker and catalyst concentration has been determined to be unity and 0.24, respectively. The activation energy of the reaction has been found to be zero.

Photocrosslinking behavior of chlorinated polydimethylsiloxanes (CPDMS) has been studied. It was found that the viscous CPDMS were readily crosslinked to form the rubberlike materials on irradiation from a high pressure mercury lamp. The crosslinking mechanism was proposed on the basis of infrared s
