Abstract
Briefly stated, the present invention comprises novel compounds useful as two-cycle oil additives obtained by reacting an alkyl acrylamide with a compound selected from the group consisting of polyalkylenepolyamines, polyalkylenepolyamines functionalized with polyalkyl acid anhydrides and polyalkylenepolyamines and a polyalkyl acid anhydride.
Claims8
A two-cycle oil composition comprising a major portion of a two cycle oil and a minor amount of an additive obtained by reacting an acrylamide with a compound selected from the group consisting of a polyalkylene polyamine, a polyalkylene acid anhydride, and mixtures thereof, wherein the acrylamide has the formula:
- ##STR3## wherein R1 is an alkyl group having from 12 to 24 carbon atoms and R2 is H or a C.sub.1 to C.sub.3 alkyl group.
A compound obtained by reacting acrylamide with a reagent selected from the group consisting of polyalkylene polyamine functionalized with a polyalkylene acid anhydride;
- and a mixture of a polyalkylenepolyamine and a polyalkylene acid anhydride, wherein the acrylamide has the formula:
- ##STR5##
The compound of claim 5 wherein the polyamine is functionalized with a polyalkylene acid anhydride.
A two-cycle additive concentrate containing from about 5 wt % to about 80 wt % of a solvent and from about 10 wt % to about 95 wt % of a compound obtained by reacting acrylamide with a reagent selected from the group consisting of polyalkylene polyamines;
- polyakylenepolyamine functionalized with a polyalkylene acid anhydride;
- and a mixture of a polyalkylenepolyamine and a polyalkylene acid anhydride, wherein the acrylamide is the formula ##STR6## wherein R1 is an alkyl group havinq from 12 to 24 carbon atoms and R2 is H or a C.sub.1 to C.sub.3 alkyl group.
