bioabbaubare neopentylpolyolbasierte synthetic estermischungen and lubricants

摘要

A novel biodegradable polyneopentyl polyol (PNP) ester based synthetic ester basestock that includes a PNP ester admixed with a dicarboxylic acid ester coupling agent is provided. The PNP ester-coupling agent mixture is blended further with minor amounts of a single, or mixture of, additional high molecular weight linear or branched chain ester. The final basestocks are compatible with standard lubricant additive packages and miscible with gasoline to provide biodegradable lubricants that have improved viscosity characteristics, good low temperature properties, and improved lubricity for 2-stroke engine lubricant applications.
