Abstract
N-substituted acrylamidines having the general formula: ##STR1## in which R.sub.1 is an isopropyl group, R.sub.2 and R.sub.3 each is hydrogen, ethyl, propyl, butyl, pentyl, octyl, or octadecyl. The acrylamidine is copolymerized with at least one ester of acrylic and/or methacrylic acid esters, and the copolymer has use as an oil additive and for the manufacture of molded articles, paints and adhesives.
Claims4
A composition comprising a major proportion of a lubricating oil and 0.5 to 10% by weight of a copolymer of at least one ester selected from the group consisting of acrylic and methacrylic esters of a saturated alcohol having 1-20 carbon atoms and at least one N-substituted acrylamidine having the formula:
- ##STR14## in which R.sub.1 is selected from the group consisting of branched alkyl, and R.sub.2 and R.sub.3 each can contain up to 18 atoms of carbon and is selected from the group consisting of hydrogen, alkyl, alkenyl, aryl, alkaryl, aralkyl, cycloalkyl, cycloalkenyl, bicycloalkyl, haloalkyl, haloaryl, haloalkyaryl, pyridyl, hydroxyalkyl, and hydroxyaryl, the said copolymer containing from 0.1 to 99.9% and from 99.9 to 0.1% by weight of the two monomers.
