ADDITION AGENT TO LUBRICATING OILS |
| 摘要 |
FIELD: chemical industry. SUBSTANCE: addition agent based on hydrogenated stylene-butadiene block copolymer has unsymmetric B/S-S-B structure of general formula: <EMI ID=0.367 HE=48 WI=72 TI=CHI> wherein B/S block= a<SB>1</SB>+b<SB>1</SB>+c<SB>1</SB>, molecular weight 40000-130000; S block=c<SB>2</SB>=12-37 wt %, molecular weight 8500-55000; B block=a<SB>2</SB>+c<SB>2</SB>=1-5 wt %, molecular 1000-8000; c<SB>1</SB>+c<SB>2</SB>=50-65 wt %, a<SB>1</SB>+a<SB>2</SB>= 30-50 wt % per olefinic moiety. Addition agents of claimed structure have better thermooxidizing stability and high thickening property. EFFECT: improved properties of lubricating oils. 2 tblH
