Acrylic-olefin hybrid polymers and their uses as rust preventatives

专利摘要

Polymers having an acrylic-olefin backbone prepared from a monomer composition comprising at least one C1-30 (meth)acrylic compound and at least on alpha-olefin having a chain length of at least 20 carbon atoms (a "C20+ α-olefin"). The resulting polymer has at least 30 wt% of the alpha-olefin incorporated therein. The polymers may be used in rust preventative compositions to reduce rust formation on items having metal components. ......

A polymer having an acrylic-olefin backbone prepared from a monomer composition comprising: a. at least one C1.30 (meth)acrylic compound; and b. at least one alpha-olefin having a chain length of at least 20 carbon atoms (a “C20+ a-olefin”); and wherein the resulting polymer has at least 30 wt% (or at least 35 wt%, or 40 wt%, or 45 wt%, or at least 49 or 50 wt%) of the alpha-olefin incorporated therein.2. The polymer of claim 1, wherein the at least one (meth)acrylic compound is a C1.20, or Ci-i8, or C4-12, (meth)acrylic compound, or a mixture thereof.3. The polymer of claim 1 or 2, wherein the at least one (meth)acrylic compound is (meth)acrylate, (meth)acrylic acid, (meth)acrylamide, or combinations thereof.4. The lubricating composition of any claim 1 to 3, the at least one (meth)acrylic compound is acrylic acid, acrylamide, methacrylate, methacrylic acid, methacrylamide, or combinations thereof.5. The polymer of any claim 1 to 3, wherein the at least one (meth)acrylic compound is a (meth)acrylate comprising butyl acrylate, n-butyl methacrylate, stearyl methacrylate, methyl methacrylate, or a mixture thereof.6. The polymer of claim 5, wherein the (meth)acrylate comprises butyl acrylate, n-butyl methacrylate or a mixture thereof.7. The polymer of claim 5, wherein the (meth)acrylate comprises stearyl methacrylate, methyl methacrylate, or a mixture thereof.8. The polymer of any claim 1 to 7, wherein the at least one alpha-olefin comprises a C20-28 a-olefin, C20-24 a-olefin, C24-28 a-olefin, C26-28 a-olefin, an alphaol efin having a chain length of at least 30 carbon atoms (a “C30+ a-olefin”), or a mixture thereof.9. The polymer of any claim 1 to 8, wherein the at least one alpha-olefin comprises a C24-28 a-olefin.10. The polymer of claim 9, wherein the polymer backbone comprises at least 40 wt% or at least 50 wt% of a C24-28 a-olefin.11.
