  新型两亲远螯聚氧杂环丁烷的合成与表征

  摘要：

  合成并表征了具有半氟化（FOx）和烷基醚侧基（ME2Ox）的醇封端远螯聚氧杂环丁烷。由于亲水和疏水重复单元的结合，它们是两亲的远螯。通过端基分析，通过NMR光谱表征ME2Ox / FOx远螯共聚物的组成和分子量。差示扫描量热法显示T g降低随着ME2Ox掺入量的增加，并为共聚物的结构提供了证据。在两种极性不同的溶剂中测定单体反应率。在二氯甲烷中，衍生自5FOx单体的活性端优先与ME2Ox反应，而ME2Ox衍生的端则没有选择性显示。ME2Ox的反应比为0.97，5FOx的反应比为0.12。在甲基环己烷中，单体反应性比是理想共聚的更多特征。对于ME2Ox，参数为1.65；对于5FOx，参数为0.49。

• Fluorinated diamines and polymers formed therefrom
  申请人：Aerojet General Corporation

  The present invention provides fluorinated diamines and polymers formed therefrom, such as polyureas, polyurethane ureas, polyamides, polyimides, etc. The fluorinated diamines of the present invention are highly nucleophilic and are structured to provide polymeric materials having optimum surface properties. In the fluorinated diamines of the present invention, the end groups are primary amino groups which are substantially removed from the perfluoroalkyl groups. Moreover, the fluorine is present in the side chains which allows the fluorocarbon segments to migrate to the polymer/air interface, thereby providing polymer surfaces with high fluorine concentrations. As such, the polymers formed from the fluorinated diamines of the present invention have a variety of commercial applications as stain and oil resistant coatings, fouling release coatings, encapsulants for electrical devices, curing agents for epoxies, etc.

  本发明提供了由氟代二胺形成的聚合物，例如聚脲，聚氨酯脲，聚酰胺，聚酰亚胺等。本发明的氟代二胺具有高亲核性，并且被设计成提供具有最佳表面性能的聚合材料。在本发明的氟代二胺中，末端基团是主要氨基团，其与全氟烷基团相隔甚远。此外，氟在侧链中存在，这使得氟碳段可以迁移到聚合物/空气界面，从而提供具有高氟浓度的聚合物表面。因此，由本发明的氟代二胺形成的聚合物具有多种商业应用，如防污油涂层，防污涂层，电器封装材料，环氧树脂的固化剂等。

  This application is directed to novel fluorinated polymers and prepolymers derived from mono-substituted oxetane monomers having fluorinated alkoxymethylene side-chains and the method of making these compositions. The mono-substituted fluorinated oxetane monomers having fluorinated alkoxymethylene side-chains are prepared in high yield by the reaction of a fluorinated alkoxides with either 3-halomethyl-3-methyloxetane premonomers or aryl sulfonate derivative of 3-hydroxymethyl-3-methyloxetane premonomers. Preparation of a mono-substituted 3-bromomethyl-3-methyloxetane premonomer via a simple, high yield process amenable to commercial scaleup is also disclosed. The fluorinated oxetane monomers of this invention can be readily homo/co-polymerized in the presence of a Lewis acid and polyhydroxy compounds to obtain hydroxy-terminated polyether prepolymers having fluorinated alkoxymethylene side chains. Additionally, the fluorinated oxetane monomers can be copolymerized with non-fluorinated monomers such as tetrahydrofuran to give polyether prepolymers with improved hydrocarbon compatibility. These prepolymers are polydisperse and exhibit number average molecular weights from 5,000 to about 50,000. These prepolymers are amorphous oils with primary hydroxy end-groups and thus function efficiently as the soft block for the synthesis of a variety of thermoset/thermoplastic elastomers and plastics having the characteristics of very low surface energy, high hydrophobicity, low glasss transition temperature and low coefficient of friction. The polyurethanes derived from the prepolymers of this invention are elastomeric and, in addition to the above characteristics, exhibit high moisture resistance, high tear strength and excellent adhesion to a variety of substrates.

  该申请涉及一种新型的含氟聚合物和预聚物，其源自于具有含氟烷氧甲基侧链的单取代氧杂环戊烷单体，并且涉及制备这些组合物的方法。这些具有含氟烷氧甲基侧链的单取代氟氧杂环戊烷单体可通过将含氟烷氧化物与3-卤代甲基-3-甲氧基氧杂环戊烷预聚物或3-羟甲基-3-甲氧基氧杂环戊烷预聚物的芳基磺酸衍生物反应而高产率制备。此外，还公开了一种简单、高产率的方法，通过该方法可以制备单取代3-溴甲基-3-甲氧基氧杂环戊烷预聚物，该方法适用于商业规模生产。本发明的含氟氧杂环戊烷单体可以在路易斯酸和多羟化合物的存在下容易地进行同聚/共聚反应，以获得具有含氟烷氧甲基侧链的羟基终止的聚醚预聚物。此外，含氟氧杂环戊烷单体可以与四氢呋喃等非含氟单体共聚，以获得具有改善烃类相容性的聚醚预聚物。这些预聚物是多分散的，并且具有5,000至约50,000的数平均分子量。这些预聚物是无定形油状物，具有主要的羟基末端，因此可以有效地作为合成各种热固性/热塑性弹性体和塑料的软块，具有极低的表面能、高疏水性、低玻璃转移温度和低摩擦系数的特性。本发明的预聚物衍生的聚氨酯具有弹性，并且除了上述特性外，还具有高湿度抗性、高撕裂强度和对各种基材的优异粘附性。

  Monofunctional polyfluorooxetane oligomers, polymers, and copolymers are prepared by the cationic polymerization of fluorooxetane monomers with a monoalcohol. In addition to serving as an initiator, the monoalcohol can also serve as a solvent for the fluorooxetane or other monomers to produce oligomers, polymers, or copolymers having low cyclic content. Suitable comonomers generally include various cyclic ethers. The polyfluorooxetane oligomer, polymer, or copolymer having a single hydroxyl end group can be functionalized with a variety of compounds so as to yield a functional end group such as an acrylate, a methacrylate, an allylic, an amine, etc., with the functionalized oligomer or polymer being suitable for use in radiation curable or thermal curable coating compositions. These functionalized polymers can be copolymerized and cured to provide improvements in wetting and surface properties.
