  A polyester is produced by co-condensation-polymerizing a starting polyester (1) being a linear polyester which may have a branched group(s), (2) having a number-average molecular weight of 300 to 1,400 and (3) containing 10 to less than 25 mole percent, based on the total diol components of the starting polyester, of a dihydric alcohol having the following formula: HO-(CH2)n-OH, in which n is an integer of 2 to 6, with a tri- or more-valent monomer(s) selected from a tri- or more valent carboxylic acid, a derivative thereof and a tri- or more-valent alcohol. The polyester is useful for an electrophotographic developer composition and toner.

  The present invention claims an organopolysiloxane compound having at least one group having the formula wherein R3 is a divalent hydrocarbon group having from 1 to 20 carbon atoms, R5 and R6 are selected from a hydrogen atom or a group having the formula -(CnH2n+1) where n has a value from 1 to 30, R4 is selected from hydrogen atom, alkyl group or aryl group, d has a value from 0 to 150 and e has a value from 0 to 150, with the proviso that the value of d+e is greater than zero. These compounds reduce the amount of foam in hydrocarbon fuels, especially in diesel or jet fuels. Our organopolysiloxane compounds function as foam control agents which display consistent compatibility and miscibility with other fuel additives which are frequently present in hydrocarbon fuels.

  本发明要求一种有机聚硅氧烷化合物，其中至少有一个基团具有以下式子 其中 R3 是具有 1 至 20 个碳原子的二价烃基，R5 和 R6 选自氢原子或具有式 -(CnH2n+1)的基团，其中 n 的值为 1 至 30，R4 选自氢原子、烷基或芳基，d 的值为 0 至 150，e 的值为 0 至 150，但 d+e 的值大于零。这些化合物可减少碳氢化合物燃料，特别是柴油或喷气燃料中的泡沫量。我们的有机聚硅氧烷化合物可用作泡沫控制剂，与碳氢化合物燃料中常见的其他燃料添加剂具有一致的兼容性和混溶性。
