STUDY OF CURING PROCESSES IN PDMS AT VARIOUS STOICHIOKETRIC RATIOS BY LONGITUDINAL ULTRASONIC WAVES Academic Article uri icon

abstract

  • Abstract Curing reactions of linear vinyl terminated poly (dimethylsiloxane) with a four functional hydride silane crosslinker at various stoichiometric ratios, were studied by wave propagation at ultrasonic frequencies. Longitudinal wave velocity was found to be sensitive to the covalent endlinking, and gel point in these systems.
