Glycidyl esters of alpha, alpha branched acids compositions
View Patent ↗The invention relates to compositions of α,α-branched alkane carboxylic acids glycidyl esters with a define isomeric composition where the sum of the concentration of the blocked and of the highly branched isomers is at least 50%, preferably above 60% and most preferably above 75% on total composition.
1. A composition of α,α-branched alkane carboxylic glycidyl esters from butene oligomers, comprising a glycidyl ester mixture of neo-acid based on dimer or trimer of butene having both blocked isomers and highly branched isomers wherein a sum of a concentration of the blocked isomers and of the highly branched isomers is at least 60% weight based on the weight of the composition, wherein a blocked isomer comprises neo-acids having tertiary or quaternary carbon atoms in the β position and a highly branched isomer comprises neo-acids having at least 5 methyl groups, wherein the glycidyl ester mixture comprises 2,2-dimethyl 3,3-dimethyl pentanoic acid glycidyl ester in 10 to 14 weight %, 2-methyl 2-isopropyl 3-methyl butanoic acid glycidyl ester in 20 to 28 weight % and 2-methyl 2-ethyl 3,3-dimethyl butanoic acid glycidyl ester in 17 to 22 weight % based on the weight of the glycidyl ester mixture, wherein the total amount of the glycidyl ester mixture is 100 weight %.
2. A binder composition for paints or adhesives comprising the composition of claim 1 as a reactive diluent or as a monomer.
3. A resin comprising the composition of claim 1 wherein the resin is selected from the group consisting of a polyester polyol resin, an acrylic polyol resin, a polyether polyol resin, or an epoxy resin formulation.
4. A composition of α,α-branched alkane carboxylic glycidyl esters from butene oligomers, comprising a glycidyl ester mixture of neo-acid based on dimer or trimer of butene having both blocked isomers and highly branched isomers wherein a sum of a concentration of the blocked isomers and of the highly branched isomers is at least 60% weight based on the weight of the composition, wherein a blocked isomer comprises neo-acids having tertiary or quaternary carbon atoms in the β position and a highly branched isomer comprises neo-acids having at least 5 methyl groups, wherein the glycidyl ester mixture comprises 2,2-dimethyl 3-methyl 4-methyl pentanoic acid glycidyl ester in 10 to 18 weight % and 2,2-dimethyl 4,4-dimethyl pentanoic acid glycidyl ester in 15 to 22 weight % based on the weight of the composition.
5. A binder composition for paints or adhesives comprising the composition of claim 4 as a reactive diluent or as a monomer.
6. A resin comprising the composition of claim 4 wherein the resin is selected from the group consisting of a polyester polyol resin, an acrylic polyol resin, a polyether polyol resin, or an epoxy resin formulation.
