Abstract
This invention relates to non-polymeric, asymmetrical, low freezing, high boiling, aliphatic compounds containing from 2 to 5 pyrrolidonyl rings and from 13 to 40 carbon atoms which melt below 0.degree. C. and which boil above 300.degree. C. at atmospheric pressure and to the synthesis and use of said liquid polypyrrolidonyl compounds.
Claims11

C. at atmospheric pressure and having the formula ##STR9## wherein R in the asymmetrical structure is selected from the group of a C.sub.5 to C.sub.25 aliphatic hydrocarbon, and a C.sub.5 to C.sub.25 aliphatic hydrocarbon ether or polyether and n is an integer having a value of from 2 to 5.
A non-polymeric, asymmetrical compound having a freezing point below 0.degree. C. and a boiling point above 300.degree. C. at atmospheric pressure and having the formula ##STR10## wherein R is the asymmetrical structure is selected from the group of a C.sub.5 to C.sub.25 aliphatic hydrocarbon, and a C.sub.5 to C.sub.25 aliphatic hydrocarbon ether of polyether and n is an integer having a value of 3.
A non-polymeric, asymmetrical compound having a freezing point below 0.degree. C. and a boiling point above 300.degree. C. at atmospheric pressure and having the formula ##STR11## wherein R in the asymmetrical structure is selected from the group of a C.sub.5 to C.sub.25 aliphatic hydrocarbon ether or polyether and n is an integer having a value of from 2 to 5.
