Abstract
Methylphenylvinyl raw rubber (MPVRR) is one of the important materials for preparation of phenyl-containing additive molding liquid silicone rubber (AMLSR). Two methods, bulk polymerization (BP) and ring-opening polymerization (ROP), were used to prepare MPVRR. The effects of formulation, temperature and water content on MPVRR properties for BP method were investigated and the product was characterized by Fourier Infrared Spectrometer. The effects of formulation, end capping reagent dosage, feeding sequence, reaction temperature and time on MPVRR properties for ROP method were discussed and the product was characterized by Double Beam UV-visible Spectrophotometer. The results showed that BP method could only prepare low phenyl content of MPVRR with phenyl mass percentage of 3.4%-5.2%, but ROP method could prepare both low phenyl content of MPVRR with phenyl mass percentage of 9.2% and middle phenyl content of MPVRR with phenyl mass percentage of 16.4%, which were nearly close to the theoretical values of 12% and 21.5%, respectively. The samples prepared using the two methods were proved to be MPVRR materials by the instrument analysis, respectively.
