ANTITURBULENT ADDITIVES FOR REDUCING HYDRODYNAMIC DRAG OF HYDROCARBON LIQUIDS IN PIPELINES AND METHOD FOR THEIR PRODUCING Russian patent published in 2017 - IPC C08F10/10 C08L23/22 C08K5/00 C10L1/10 F17D1/16 

FIELD: chemistry.

SUBSTANCE: method involves the use of ultra-high molecular polyisobutylene or isobutylene copolymers with higher α-olefins or mixtures of polyisobutylene with polyolefins α to produce the liquid dispersion of a (co)polymer (LD PTP) and the dry dispersion of a (co)polymer (DD PTP) and their use as an antiturbulent additive. The method is implemented by using three process versions. The LD PTP composition and the DD PTP composition are described as well.

EFFECT: simplification of obtaining PTPs, increasing their range, capabilities and temperature range when used in trans-polar pipes and in winter conditions, achievement of the higher quality and high performance of the additive.
