본 발명은 향상된 유연도 또는 경도의 코팅이 유래되는 글리시딜 에스테르를 제공하는 α,α-분지형 알칸 카르복시산을 제조하기 위한 제조방법에 관한 것이다. 여기서, 높은 경도를 제공하는 네오노난산 혼합물은 차단성 이성질체와 고도 분지형 이성질체의 총 농도가 적어도 50%, 바람직하게는 60% 이상, 가장 바람직하게는 75% 이상인 혼합물이다. 여기서, 연성 중합체를 제공하는 네오노난산 혼합물은 차단성 이성질체와 고도 분지형 이성질체의 농도가 최대 55%, 바람직하게는 40% 이하, 가장 바람직하게는 30% 이하인 혼합물이다. The invention relates to a manufacturing process for the preparation of α,α-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%.
