我们通过有机聚硅氧烷与羟基封端聚酯反应制备了一系列新型水溶性有机硅改性聚酯[聚乙二醇(PEG)-有机硅聚酯]。聚酯是通过马来酸酐和PEG（分子量= 2000、4000、6000、8000和10000）聚合获得的。这些水溶性PEG-有机硅聚酯可用作染色过程中的助剂，因为它们具有良好的表面活性，如表面张力、低发泡和润湿力。这些表面活性剂的存在也降低了酸性染料对尼龙的染色速度。这些新型 PEG-有机硅聚酯的阻滞效果和低泡特性使得这些表面活性剂可以用作现代尼龙酸性染料染色的匀染剂。
We prepared a novel series of water-soluble silicone-modified polyesters [poly(ethylene glycol) (PEG)-silicone polyesters] by reacting organopolysiloxane with a hydroxy-terminated polyester. The polyesters were obtained by the polymerization of maleic anhydride and PEGs (molecular weights = 2000, 4000, 6000, 8000, and 10000). These water-soluble PEG-silicone polyesters can be used as auxiliaries in dyeing process because they exhibit good surface activities such as surface tension, low foaming, and wetting power. The presence of these surfactants also retarded the rate of nylon dyeing with acid dyes. The retarding effect and low-foaming property of these novel PEG-silicone polyesters make it possible for these surfactants to be used as leveling agents for modern nylon dyeing with acid dyes.
