Permissible molecular weight of polyisobutylene for thickening transmission oils

  • Published:
Chemistry and Technology of Fuels and Oils Aims and scope

Conclusions

  1. 1.

    It is shown that polyisobutylene of molecular weight 8000 or more is unsuitable for obtaining thickened transmission oils; the polymer should have a molecular weight of 3000–5000 for this purpose.

  2. 2.

    It has been established that, with the exception of the viscosity, during operation in an automobile gear box the physicochemical properties of the thickened oil remain practically unchanged.

  3. 3.

    It is shown that very similar results are obtained for mechanical destruction of polyisobutylene in the gear box of a Volga automobile, on a gear stand, and in a UZDN-1 ultrasonic installation.
