Abstract
Lubricant compositions include copolymers of monomers selected from C6-C10 alkyl methacrylate monomers, and monomers selected from C10-C18 alkyl methacrylate monomers, and a base oil or comprising a copolymer obtained by combining at least monomers selected from C6-C10 alkyl methacrylate monomers, and monomers selected from C10-C18 alkyl methacrylate monomers in a mixture and co-polymerizing the monomers. The lubricant compositions may find use in lubricating two-stroke marine engines by applying the lubricant compositions to at least one component of a two-stroke marine engine.
Claims15
A lubricant composition comprising:
- from 0.01% to 10% by weight, relative to the total weight of the lubricant composition, of a copolymer of alkyl methacrylate monomers, wherein said alkyl methacrylate monomers consist essentially of:
- a. Monomers (A) selected from C6-C10 alkyl methacrylate monomers, and
- b. Monomers (B) selected from C10-C18 alkyl methacrylate monomers, the Monomers (B) consisting of a C12 alkyl methacrylate monomer or the Monomers (B) comprising a mixture of about 0.1 to 2% by weight of C10 alkyl methacrylate, about 50 to 80% by weight of C12 alkyl methacrylate, about 15 to 40% by weight of C14 alkyl methacrylate, about 2 to 12% by weight of C16 alkyl methacrylate and about 0.1 to 1% by weight of C18 alkyl methacrylate based on a total weight of the mixture,
- and the mass ratio of Monomer (B) to Monomer (A) in the copolymer is 99:1 to 10:90,
- a base oil.
