Applicant's summary and conclusion
- Conclusions:
- The viscosity of molten MeFBSA was 6.86 mPa.s (centipoise) at 45°C
- Executive summary:
Viscosity of molten MeFBSA was determine over the range of 45 - 100 °C using a Brookfield rotational viscometer. Viscosity was independent of shear rate from 12-60 RPM. No guideline was cited, but the instrumental method generally follows ASTM D-2983. Study details were limited. Therefore, the study is considered reliable with restrictions.
