A series of novel polyethylene glycol derivates was synthesized by esterification of chloroacetic acid with polyethylene glycol. Because of the good reactive activity of α-chlorin in the esters it can react with 5-fluorouracil, thus the conjugate can be obtained .

采用氯乙酸与不同分子量的聚乙二醇进行酯化反应得到氯乙酸聚乙二醇酯，由于酯中的α-氯具有良好的反应活性，将它再与抗癌药物5-氟尿嘧啶结合制备了不同分子量的高分子前药。

The macromer, methoxy polyethylene glycol methacrylate, used for polycarboxylate based superplasticizer was prepared by esterification of methacrylic acid and methoxy polyethylene glycol.

以聚乙二醇单甲醚和甲基丙烯酸为主要原料，通过酯化反应制备聚羧酸系减水剂大单体聚乙二醇单甲醚甲基丙烯酸酯。

The formation mechanism and the role of the solvents played were explored. Ethylene glycol was found to serve as the reducing agent while acetylacetone had effects on maintaining equilibrium conditions, suppressing the coalesces, enhancing the reducing ability of ethylene glycol, and directing the growth of multiply twinned palladium particles.

通过对产物形成的机理及溶剂所起的作用进行深入研究，发现乙二醇是还原剂，乙酰丙酮则具有维持平衡条件、减少团聚、增强乙二醇的还原能力及诱导钯多重孪晶的生长等作用。

Techniques:Ethylene glycol is the most important downstream products of ethylene. Although the domestic glycol production has been increasing, demand still overweighs supply. Every year there are plenty of imports to satisfy the great domestic market demand.

工艺技术简述：乙二醇是乙烯最重要的下游产品，虽然国内乙二醇产量虽呈逐年递增趋势，但仍然长期处于供不应求状态，每年都有大量的进口，国内市场基本依靠进口满足需求，市场供求矛盾较大。

The progress of study and application of catalyst on polycondensate reaction of polyester were reviewed, manufacture and application of diantimony trioxide, antimony acetate ,ethylene glycol antimony were introduced and discussed in detail, and preliminary research direction of ethylene glycol antimony was pointed out.

介绍了聚酯缩聚反应所用催化剂的研究与应用进展，详细评述了三氧化二锑、醋酸锑、乙二醇锑的研制与应用情况，初步提出了今后乙二醇锑的研究方
