Abstract
Novel compositions of matter comprising alkenyl amines are provided. They are prepared by the reaction of a halogenated polyolefin with at least one polyamine having an ether group, such as tris(6-amino-3-oxa-hexyl)amine, N,N-bis(6-amino-3-oxa-hexyl)ethanol amine, N-ethyl-N,N-bis(6-amino-3-oxa-hexyl)amine, etc. The novel compositions of matter provide detergent-dispersant additives for use in lubricating oils and fuels.
Claims20
A composition of matter comprising at least one compound of the formula:
- ##STR9## in which formula:
- R represents a C.sub.20 -C.sub.350 alkenyl group,
- R' represents a member selected from a hydrogen atom and the radical R,
- R.sub.1 and R.sub.2 represent a member selected from a hydrogen atom and a methyl radical,
- R" represents a radical of the formula:
- ##STR10## in which R'.sub.1 and R'.sub.2 represent a member selected from a hydrogen atom, the radical R and a radical of the formula:
- ##STR11## R"' represents a radical of the formula:
- ##STR12## in which R'.sub.3 and R'.sub.4 represent a member selected from a hydrogen atom, the radical R, a radical of the formulae:
