(有关国外文献概述) 一九五八年英国专利首次报导了含氟聚氨酯的合成。六十年代国外对含氟聚氨酯进行了较广泛深入的研究。在美国,以国家宇宙航空局(NASA)为中心,在Narmco,3M.以及dupont等公司中进行了这方面的研究。在苏联,乌克兰高分子研究所等单位也进行了研究。Narmco.公司,为探索耐液氧和在纯氧中不燃的新材料,从一九六三年开始,合成了数种新的含氟聚酯二醇,聚醚二醇以及含氟二异氰酸酯,并在此基础上合成了一系列含氟聚氨酯。据初步统计,现已研究的含氟聚氨酯达五、六十种之多。含氟聚氨酯已成为聚氨酯的一个分支,也已成为含氟高聚物中的一个独立研究方向。
(Overview of Foreign Literature) The first British patent in 1958 reported the synthesis of fluorinated polyurethanes. In the 1960s, fluorinated polyurethanes were studied extensively and deeply abroad. In the United States, NASA is the center of research in this area at companies such as Narmco, 3M and DuPont. In the Soviet Union, Ukrainian Institute of Polymer Research and other units were also studied. Narmco. To explore new materials resistant to liquid oxygen and flammable in pure oxygen, several new fluorine-containing polyester diols, polyether diols and fluorinated diisocyanates were synthesized since 1963, On this basis, a series of fluorinated polyurethanes were synthesized. According to preliminary statistics, fluorine-containing polyurethane has been studied up to five or sixty as many. Fluorinated polyurethanes have become a branch of polyurethanes and have also become an independent research direction in fluoropolymers.
