Abstract
(Meth)acrylate-functionalized branched polyalpha-olefins which are the reaction product of, at least, a) a (meth)acrylate source and b) a hydroxyl-functionalized branched polymerizate of, at least, i) one or more alpha-olefin monomers having at least six carbon atoms per molecule and ii) one or more unsaturated hydroxyl-functionalized comonomers are useful hydrophobic, reactive components of crosslinkable resin compositions additionally containing a polymer (such as a polyolefin) as well as curable compositions containing one or more additional types of (meth)acrylate-functionalized compounds.
Claims24
A (meth)acrylate-functionalized branched polyalpha-olefin comprising the reaction product of, at least, a) a (meth)acrylate source and b) a hydroxyl-functionalized branched polymerizate of, at least, i) one or more alpha-olefin monomers having at least six carbon atoms per molecule and ii) one or more unsaturated hydroxyl-functionalized comonomers, wherein one or more of the hydroxyl functional groups of the hydroxyl-functionalized branched polymerizate are converted to (meth)acrylate functional groups.
A method of preparing a (meth)acrylate-functionalized branched polyalpha-olefin, comprising reacting a (meth)acrylate source and a hydroxyl-functionalized branched polymerizate of, at least, i) at least one alpha-olefin monomer having at least six carbon atoms per molecule and ii) at least one unsaturated hydroxyl-functionalized comonomer, wherein one or more of the hydroxyl functional groups of the hydroxyl-functionalized branched polymerizate are converted to (meth)acrylate functional groups.
A (meth)acrylate-functionalized branched polyalpha-olefin comprised of a plurality of repeating units A in accordance with Formula (III) and a plurality of repeating units B in accordance with Formula (IV):
- wherein R is H or methyl, R4 is an alkyl group comprised of at least four carbon atoms, R5 is a direct bond or a divalent alkylene group, R6 is optionally present, but if present, is a divalent oxyalkylene group or a divalent poly(oxyalkylene) group, and R7 is H or an alkyl group.
