VISCOUS ADDITION AGENT TO HYDROCARBON OILS AND PLASTIC LUBRICANTS Russian patent published in 1999 - IPC

Abstract RU 2131453 C1

FIELD: chemical industry. SUBSTANCE: viscous addition agent includes products of thermomechanical treatment of polyethylenes in air at temperature lower than melting temperature of polyethylenes. Thickening power of viscous addition agent is by 3.5-55 times higher than that of polyisobutylenes, polymethacrylates and vinypols, and thermomechanical stability is higher by 1.3-2.0 times. EFFECT: wide range of raw materials and reduced energy consumption in preparing viscous addition agent.
