    Abstract: Detergent or micelle free cleaning media based on detergent free and/or micelle free liquid CO2 and including from 0.01 to 5% by weight of the formulation of a cleaning additive which is at least one multi-ester having a molecular weight of not more than 750 can be used in dry cleaning of textiles. Desirable cleaning additives are of the formula (1): R1(XR2)n where X, R1, R2, and n have defined meanings, particularly to be esters of multi-carboxylic acids and mono-hydroxy alcohols or esters of mono-carboxylic acids and multi-hydroxy alcohols.

    Abstract: A block copolyester comprises a hard segment and a soft segment, wherein the melting point of the copolyester is greater than or equal to 200° C., and the glass transition temperature of the copolyester is less than or equal to −40° C. The hard segment is preferably polyethylene terephthalate, polybutylene terephthalate, or polyethylene naphthalate. The soft segment is preferably formed from at least one dimer fatty acid and/or dimer fatty diol and/or equivalent thereof. The copolyester is especially suitable for use in automotive parts, particularly where thermal stability is required.

    Abstract translation: 嵌段共聚酯包括硬链段和软链段,其中共聚多酯的熔点大于或等于200℃,共聚聚酯的玻璃化转变温度低于或等于-40℃。 硬链段优选为聚对苯二甲酸乙二醇酯,聚对苯二甲酸丁二醇酯或聚萘二甲酸乙二醇酯。 软链段优选由至少一种二聚体脂肪酸和/或二聚体脂肪二醇和/或其等同物形成。 共聚酯特别适用于汽车部件,特别是需要热稳定性的部件。
