摘要：

The possibility of sulfur atom introduction into molecule of oligoisobutenes in the course of ozonolysis of isobutene copolymers with isoprene at room temperature was studied. Sulfur-containing oligoisobutenes (OIS) were prepared by ozonolysis of butyl rubber BK 1675 in benzene BR-1 in the presence of butanol and sulfur. Results of comparative tests of 10 % OIS solution and oligoisobutenes with terminal carboxylic and ketone groups (CAKG) are presented. OIS exceed CAKG in all the indices. OIS synthesized possess thickening, antioxidating, antiscore and antiwear action.
