The HBr-initiated solid-state polymerization of hexamethylcyclotrisiloxane has been investigated. Up to about 70% conversion, the rate of polymerization is found to be constant but the molecular weight of the polymer formed was observed to increase with conversion. Temperature did not have a marked effect on the polymerization rate as an activation energy of only 2.8 kcal/mole was observed, whereas the rate was found to be exponentially related to the HBr vapor pressure. The HBr and the radiation-initiated solid-state polymerization are compared.
