    摘要： The present invention relates to mixtures of citric esters of the formula I, in which each of R1, R2 and R3 is an aliphatic C5 or C9 moiety, wherein the average chain length of the aliphatic moieties in the mixture is in the range from greater than 5 to 7, and the average degree of branching of the aliphatic C9 moieties is in the range from 0.9 to 2.2. The present invention also relates to the use of the citric ester mixture as a plasticizer in plastics compositions.

    摘要： The present invention relates to mixtures of citric esters of the formula I, in which each of R1, R2 and R3 is an aliphatic C5 or C9 moiety, characterized in that the average chain length of the aliphatic moieties in the mixture is in the range from greater than 5 to 7, and the average degree of branching of the aliphatic C9 moieties is in the range from 0.9 to 2.2.The present invention also relates to the use of the citric ester mixture according to the invention as plasticizer in plastics compositions.The present invention also relates to a composition comprising the citric ester mixture according to the invention in a mixture with further components, comprising plasticizers from the group of the alkyl esters of aromatic polycarboxylic acids, of the cyclohexanepolycarboxylic acids, of benzoic acid or of adipic acid, and also to the use of this type of plasticizer composition in plastics compositions, in adhesives, in sealing compounds, in coatings, in paints, in plastisols or in inks. Plastics products produced from the plasticizers according to the invention can be, for example: profiles, gaskets, food packaging, foils, toys, medical items, roof sheeting, synthetic leather, floor coverings, underbody protection, coated textiles, wallpapers, cables and wire sheathing.

    摘要： The present invention relates to a process for the preparation of methacrylic acid or methacrylic esters, comprising the process steps of IA) preparation of 3-hydroxyisobutyric acid by a process comprising the process step of bringing a cell which has been genetically modified in comparison with its wild type in such a way that it is capable of forming more 3-hydroxyisobutyric acid, or polyhydroxyalkanoates based on 3-hydroxyisobutyric acid in comparison with its wild type, into contact with a nutrient medium comprising, as carbon source, carbohydrates, glycerol, carbon dioxide, methanol, L-valine or L-glutamate under conditions under which 3-hydroxyisobutyric acid or polyhydroxyalkanoates based on 3-hydroxyisobutyric acid are formed from the carbon source, if appropriate, isolation of the 3-hydroxyisobutyric acid from the nutrient medium and also, if appropriate, neutralization of the 3-hydroxyisobutyric acid, IB) dehydration of the 3-hydroxyisobutyric acid with formation of methacrylic acid and also, where appropriate, esterification methacrylic acid. The invention also relates to a process for the preparation of polymethacrylic acid or polymethacrylic esters.
