The rotational viscometer which had a uniform stress, designed by Dr. W. Philippoff was used for measuring the viscosities of 6% L-200 in PRIMOL 355 and Lekutherm x-30. Viscosities of 6% L-200 in PRIMOL 355 (polyisobutylene) was measured to check the change of material that was left in the visometer for almost two years. The result showed that the new viscosities are higher than the older results.
