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:
A method includes scanning a region of interest, during a contrast agent based perfusion scan, at a predetermined temporal sampling rate during contrast agent uptake in the region of interest, and generating time frame data indicative of the scanned region of interest. The method further includes identifying a predetermined change in an amount of the contrast agent in the region of interest from the time frame data. The method further includes scanning the region of interest at a lower temporal sampling rate, which is lower than the temporal sampling rate during the contrast agent uptake, in response to identifying the predetermined change in the amount of the contrast agent in the region of interest.
摘要:
A method is disclosed that includes decomposing, with a decomposer, agent-based time series projection data for an object or a subject into at least an agent based component. A projection data decomposer includes a time series decomposer that determines agent-based projection data based on agent-based time series projection data based on at least two energy dependent components. A computer readable storage medium containing instructions which, when executed by a computer, cause the computer to perform the act of determining an agent-based component of agent-based time series projection data utilizing at least two components of the agent-based time series projection is provided.
