  • Publication number: 20220363918
    Abstract: The invention relates to compositions of ?,?-branched alkane carboxylic acids glycidyl esters which derived from rosin and or hydrogenated rosin reacted with an epihalohydrin. The above glycidyl esters compositions can be used for example, as monomer in binder compositions for paints or adhesives, as reactive diluent or as acid scavenger. This invention is also about the uses of rosin and or hydrogenated rosin glycidyl ester in combinations with polyester polyols, or acrylic polyols, or polyether polyols.

  • Publication number: 20190119510
    Abstract: The invention relates to compositions of ?,?-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.

  • Publication number: 20140316030
    Abstract: The invention relates to a manufacturing process for the preparation of ?,?-branched alkane carboxylic acids providing glycidyl esters with an improved softness or hardness of the coatings derived thereof. In which the mixture of neononanoic acid providing a high hardness is a mixture 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%. In which a mixture of neononanoic acids providing soft polymers is a mixture where the concentration of blocked and highly branched isomers is maximum 55%, preferably below 40% and most preferably below 30%.

  • Patent number: 8802872
    Abstract: Accordingly, the invention relates to a process for the preparation of a glycidyl ester of a branched monocarboxylic acid by reacting an aliphatic monocarboxylic acid of the formula R1R2R3CCOOH, wherein R1, R2, and R3 each independently represent an alkyl radical of normal or branched structure containing from 1 to 20 carbon atoms and an epoxyalkyl halide containing from 3 to 13 carbon atoms in the presence of a catalyst, wherein a greater than stoichiometric amount of epoxyalkyl halide is reacted with the acid (e.g., preferably in the molar ratio of epoxyalkyl halide to acid that is in the range of from 1.02:1 to 1.50:1) to form an intermediate reaction product comprising a halohydrin, the epoxyalkyl halide is added to the acid with appropriate cooling of the reactants and/or the reaction mixture to keep the temperature of the reaction mixture below 80° C., whereupon the epoxyalkyl halide and the acid are reacted at a temperature below 80° C. (preferably in the range of from 55 to 75° C.
