摘要： An improved process is provided for the preparation of siloxane-oxyalkylene and siloxane-alkyl copolymer compositions via a hydrosilation reaction in the presence of high boiling point natural vegetable oils as the reaction solvent. The reaction solvent need not be removed from the block copolymer product, and indeed is beneficial to remain with the copolymer particularly when the copolymer is used as a surfactant for polyurethane foam formulations. Soybean oil and linseed oil are the preferred high boiling natural oil solvents when the copolymer product is to be used in the preparation of the surfactants for polyurethane foams. High resiliency polyurethane foam prepared with these natural oils present in the surfactant preparation afforded improved compression sets, wet compression sets and humid aged compression sets. Additionally, the use of the surfactants made with natural oils as a reaction solvent or consequently surfactants post diluted with natural oils when employed in the preparation of polyurethane foam afforded foams with greatly reduced amounts of “glass fogging”.
摘要翻译：提供了一种改进的方法，用于在作为反应溶剂的高沸点天然植物油存在下，通过氢硅化反应制备硅氧烷 - 氧化烯和硅烷 - 烷基共聚物组合物。反应溶剂不需要从嵌段共聚物产物中除去，实际上有利于保留共聚物，特别是当该共聚物用作聚氨酯泡沫制剂的表面活性剂时。当共聚物产品用于制备用于聚氨酯泡沫的表面活性剂时，大豆油和亚麻籽油是优选的高沸点天然油溶剂。使用表面活性剂制剂中存在的这些天然油制备的高弹性聚氨酯泡沫可提供改进的压缩套，湿压缩套和湿老化压缩套。另外，当用于制备聚氨酯泡沫时，用天然油制成的表面活性剂作为反应溶剂或随后用天然油稀释后的表面活性剂的使用提供了大量减少量的“玻璃雾化”的泡沫体。
