Summary

  1. 1.

    Viscosity-index improvers have been obtained by modification of polyisobutylene, specifically, by copolymerizing isobutylene with o-, m-, and p-isopropenyltoluenes and isopropenyl-p-xylene. The thermal stability of the homopolymers and copolymers has been studied by heating samples of these materials and of their solutions in Turbine Oil L, the changes being followed by viscometry and thermogravimetry.

    It has been established that the viscosity loss upon heating solutions of these copolymers in oil is substantially less than that for a polyisobutylene solution.

     
  2. 2.

    When the copolymers are heated in air or in argon, volatile products are formed in greater amounts than from polyisobutylene under similar heating conditions.
