Reactive (meth)acrylate monomer compositions and preparation and use thereof
View Patent ↗The present invention relates to new (meth)acrylate compositions, their preparation and their use in ultraviolet light curable applications such as coatings, inks and adhesives.
1. A process for preparing a reactive monomer composition comprising:
a. reacting an alkanolamine with a compound having at least one reactive hydroxy group or moiety, the compound being selected from the group consisting of hydroxy-functionalized triglycerides, hydroxy-functionalized fatty acids and hydroxy-functionalized fatty acid esters, to convert the compound to an amide polyol; and
b. reacting the amide polyol with an α, β-unsaturated acylating agent to convert the amide polyol to an amide poly-α, β-unsaturated acylate; and
wherein the reactive monomer composition comprising an amide poly-α, β-unsaturated acylate represented by formula I:
wherein R 1 is a hydrocarbylene moiety; R 2 is hydrogen or a hydrocarbyl moiety; R 3 is nil or a hydrocarbylene moiety; R 4 is a hydrocarbylene moiety; R 5 is H, a hydrocarbyl moiety or a moiety represented by Formula II:
wherein R 4 is as defined above and R 7 , R 8 and R 9 are independently hydrogen or a hydrocarbyl moiety; R 6 is a moiety having Formula III:
wherein R 7 , R 8 and R 9 are independently defined as above; and m, n, and o are independently 0 or 1 provided, however that a sum of m, n and o is a positive integer greater than zero.
2. The process of claim 1 , further comprising a precursor step of preparing the compound by at least partial reductive hydroformylation of a starting material selected from the group consisting of unsaturated vegetable oils, fatty acids and fatty acid esters.
3. The process of claim 2 , wherein the starting material is at least one vegetable oil and the vegetable oil is an unsaturated oil selected from the group consisting of safflower oil, sunflower oil, soybean oil, linseed oil, peanut oil, olive oil, tobaccoseed oil, cottonseed oil, coconut oil, rapeseed oil, canola oil, corn oil, and lesquerella oil and modified versions of such oils.
4. The process of claim 2 , wherein the starting material is at least one unsaturated methyl ester selected from the group consisting of methyl oleate, methyl 10-undecenoate, methyl 9-decenoate, methyl linolenate, and methyl linoleate.
5. The process of claim 1 , wherein the compound is at least one member selected from the group consisting of castor oil, ricinoleic acid or a ricinoleic acid ester.
6. The process of claim 1 , wherein the compound is hydroxymethyl stearate or hydroxymethyl methyl stearate.
7. The process of claim 1 , wherein the α, β-unsaturated acylating agent is at least one of ethyl acrylate, methyl methacrylate, or an acid halide selected from the group consisting of acryloyl chloride or methacryloyl chloride.
8. The process of claim 1 , wherein the alkanolamine is at least one of ethanolamine, 1,2-propanolamine or diethanolamine.
9. The process of claim 1 , wherein the reactive monomer composition comprises an amide poly-a,b-unsaturated acylate represented by formula I, wherein R 1 is a hydrocarbylene moiety; R 2 is a hydrogen or hydrocarbyl moiety; R 3 is nil or methylene; R 4 is ethylene or propylene, R 5 is hydrogen, methyl or a moiety represented by Formula II wherein R 4 is ethylene, R 7 is hydrogen or methyl and R 8 and R 9 are hydrogen; and R 6 is a moiety represented by Formula III wherein R 7 is hydrogen or methyl and R 8 and R 9 are hydrogen.
