The invention relates to compositions of α,α-branched alkane carboxylic acids glycidyl esters with a defined isomeric composition where the sum of the concentration of the blocked and of the highly branched isomers is maximum 55% preferably below 40%, and most preferably below 30%. The mixture of neononanoic acid glycidyl esters comprising at least 2,2-dimethyl heptanoic acid glycidyl ester and 2-methyl 2-ethyl hexanoic acid glycidyl ester and 2-methyl 2-ethyl 3-methyl pentanoic acid glycidyl esters.
1 . A composition of α,α-branched alkane carboxylic glycidyl esters from butene oligomers, comprising a glycidyl ester mixture of neo-acid derived from a dimer (C9) or trimer (C13) of butene having both blocked isomers and highly branched isomers wherein a sum of a concentration of blocked isomers and the concentration of highly branched isomers of the glycidyl ester mixture is 55% weight or less based on the weight of the composition, wherein the glycidyl ester mixture comprises 2,2-dimethyl heptanoic acid glycidyl ester in 4 to 10 weight %, 2-methyl 2-ethyl hexanoic acid glycidyl ester in 40 to 70 weight % and 2-methyl 2-ethyl 3-methyl pentanoic acid glycidyl esters (sum of stereoisomers) in 10 to 25 weight % based on the weight of the composition.
2 . A binder composition for paints or adhesives comprising the composition of claim 1 as a reactive diluent or as 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.
4 . A composition of α,α-branched alkane carboxylic glycidyl esters from butene oligomers, comprising a glycidyl ester mixture of neo-acid derived from a dimer (C9) or trimer (C13) of butene having both blocked isomers and highly branched isomers wherein a sum of a concentration of blocked isomers and the concentration of highly branched isomers of the glycidyl ester mixture is 55% weight or less based on the weight of the composition, wherein the glycidyl ester mixture comprises 2,2-dimethyl heptanoic acid glycidyl ester in 5 to 10 weight %, 2-methyl 2-ethyl hexanoic acid glycidyl ester in 45 to 65 weight % and 2-methyl 2-ethyl 3-methyl pentanoic acid glycidyl esters (sum of stereoisomers) in 12 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 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.

A composition of α,α-branched alkane carboxylic glycidyl esters from butene oligomers, comprising a glycidyl ester mixture of neo-acid derived from a dimer (C9) or trimer (C13) of butene having both blocked isomers and highly branched isomers wherein a sum of a concentration of blocked isomers and the concentration of highly branched isomers of the glycidyl ester mixture is 55% weight or less based on the weight of the composition, wherein the glycidyl ester mixture comprises 2,2-dimethyl heptanoic acid glycidyl ester in 6 to 9 weight %, 2-methyl 2-ethyl hexanoic acid glycidyl ester in 47 to 61 weight % and 2-methyl 2-ethyl 3-methyl pentanoic acid glycidyl esters (sum of stereoisomers) in 14 to 21 weight % based on the weight of the composition.
8 . A binder composition for paints or adhesives comprising the composition of claim 7 as a reactive diluent or as monomer.
9 . A resin comprising the composition of claim 7 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.
