KINETICS OF POLYCONDENSATION OF HYDROXYFUNCTIONAL POLYDIMETHYLSILOXANE

摘要

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.
