Abstract
The paper presents results concerning the synthesis and characterization as polymer processing aids (lubricants) and/or as tribological lubricants of some monoesters of different monocarboxylic acids with variable length, along with some special aliphatic-aromatic alcohols with a complex structure and/or with superior (larger) alcohols (exclusively aliphatic). The monocarboxylic acids considered were n-butyric, n-octanoic and oleic, respectively, while the alcohols taken into consideration were isodecyl (iso-C10), isotridecyl (iso-C13), as for the aliphatic group, 2-phenoxy-ethanol, 2-[(o-sec-butyl)phenoxy]ethanol, and 2-[(p-nonyl)phenoxy]ethanol, respectively, as for the complex aliphatic-aromatic group. Under these circumstances it became possible to investigate the influence of the structure on the main physico-chemical properties of these synthetic oils as well as on their lubricating characteristics. The results recorded fully certified the validity of the research program. Keywords: complex monoesters, synthetic oils, lubricants, phenoxy-ethanols
