Patent

CA 2238024

This invention provides a process for preparing a solvated isotropic pitch having a fluid temperature at least 40 °C lower than the same pitch in the non-solvated state. Additionally, the present invention provides a solvated isotropic pitch which may be formed into carbon artifacts which do not require oxidative stabilization prior to carbonization.

Cette invention, qui a trait à un procédé de préparation d'un brai isotrope solvaté possédant une température du fluide inférieure d'au moins 40 DEG C à celle du même brai non solvaté, concerne, de surcroît, un brai isotrope solvaté pouvant être façonné en articles en carbone n'exigeant pas de stabilisation oxydative avant la carbonisation.
