COMPOSITIONS OF HYDROCARBON OIL UNDERSTANDING A HYDROCARBON OIL AND A POLYMERIC ADDITIVE, POLYMERS OF ONE OR MORE OLEFINES INTENDED FOR USE AS ADDITIVES IN A PARAFFINIC HYDROCARBONIDE OIL PREPARED BY POLYMERIC PROOFER

摘要

Hydrocarbon oil compositions which contain as additive a polymer of carbon monoxide and one or more C10+ alpha -olefins in which the units originating from carbon monoxide and the units originating from the olefin(s), occur in a substantially alternating way, show an improved pour point, cold filter plugging point and/or cloud point.
