No full textPhase transformations in unsaturated polyester resins during the cure
No full textThe phase transformations occurring during the cure of an unsaturated polyester resin have been investigated by different techniques,
including high frequency dynamic–mechanical analysis by ultrasonic wave propagation. The increase of longitudinal sound velocity can be
attributed to the increase of longitudinal modulus L while irreversible viscous losses are responsible for the increase of sound attenuation. A
correspondence between the changes in the velocity and attenuation and the phase transformations (gelation and vitrification) can be observed.
The ultrasonic properties have been compared with the gel time values obtained from parallel-plate rheological measurements. Finally, a DSC
analysis has been carried out to compare the evolution of degree of reaction with that of the ultrasonic modulus
