Hello everyone,
I want to know if the analysis DSC can give the approximatives informations about the ratio of composants in the blends ABS-PC. I used Δcp PC pure (about 0.29J/gK in literature) and Δcp PC blend (about 0.10J/gK in analysis) and I acquired a report ABS/PC=2/1. I don't know if this calculation is correct and if the results could be considered.
Also I know that the PC glass transition temperature is lowered by about 3°C due to interaction with the ABS (145°C drops to 142°C). It is normal, but when the Tg decreases much more, with about 8°C? What happened? The PC was degraded during the injection?
Thank you.
