Abstract
The viscosity of a 7 % gelatin solution has been measured in the very close vicinity of the gelation transition, by rotational relaxation of ferromagnetic particles imbedded in the mixture. The viscosity critical exponent s = 0.95 ± 0.10 which is obtained over 3 decades in temperature, is well accounted for by numerical calculations in the effective field treatment of percolation theoryKeywords
