    • A description is given of a fluorine-modified one- or two-component polyurethane resin having improved surface properties, which is obtainable by a) preparing a fluorine-modified polyurethane prepolymer having free isocyanate groups or free amino and/or hydroxyl groups, or a fluorine-modified polyol mixture having free hydroxyl groups (binder), and by b) preparing a fluorine-modified polyurethane resin having a polymer-bonded fluorine content of 1% to 4% by weight in the system as a whole by reacting the fluorine-modified polyurethane prepolymer from stage a3) in the case of a one-component application with atmospheric moisture, or reacting the fluorine-modified polyurethane prepolymer or polyol mixture (binder) in the case of a two-component application with a crosslinker component (D) (curing agent), with a formulating component (F)(ii) in the presence if desired of a solvent component (L)(iii) and also of a catalyst. Through the use of suitable fluorinated macromonomers in the one- or two-component polyurethane resins of the invention it is possible to produce hard coating systems and/or surfaces having very low surface tensions and very high contact angles. Furthermore, the dirt pickup tendency of these polyurethane resins is also significantly reduced as compared with the known prior art.
    • 对具有改善的表面性质的氟改性单组分或双组分聚氨酯树脂进行描述,其可通过以下步骤获得:a)制备具有游离异氰酸酯基或游离氨基和/或羟基的氟改性聚氨酯预聚物,或 具有游离羟基的氟改性多元醇混合物(粘合剂),以及b)通过使该氟改性多元醇混合物中的氟 - 在具有大气湿度的单组分施用的情况下,或者在双组分的情况下使氟改性的聚氨酯预聚物或多元醇混合物(粘合剂)反应,从阶段a 3阶段的改性聚氨酯预聚物) 在需要溶剂组分(L)(iii)和催化剂的情况下,用交联剂组分(D)(固化剂)与配制组分(F)(ii)的应用。 通过在本发明的单组分或双组分聚氨酯树脂中使用合适的氟化大分子单体,可以生产具有非常低的表面张力和非常高的接触角的硬涂层体系和/或表面。 此外,与已知的现有技术相比,这些聚氨酯树脂的污垢吸收趋势也显着降低。

    • A process is described for producing homo-, co- and block copolymers by controlled radical polymerization in aqueous solution, wherein a monomer component (A) consisting of at least one radically polymerizable monomer, an initiator component (B) consisting of at least one radical initiator, a polysaccharide component (C) consisting of at least one cyclic polysaccharide (derivative) and a regulator component (D) consisting of at least one compound of the general formula (Ia) or/and (Ib) are reacted in the presence of water, in which R1 to R6 can each independently denote hydrogen, an optionally substituted C1-C20 alkyl residue, C3-C8 cycloalkyl residue, C7-C34 aralkyl residue or optionally an aromatic C6-C14 hydrocarbon residue and R2 and R5 can additionally denote polymer residues having an average molecular mass (number average) of 100 to 50,000 Daltons, and at least two but at most four of the residues R1 to R6 represent an aromatic hydrocarbon residue. In this manner it is possible to produce polymers with a very narrow molecular weight distribution. Moreover, due to the much lower amounts of initiator and regulator compared to the prior art, the polymers contain only very small amounts of regulator and initiator decomposition products.
    • 描述了通过在水溶液中控制自由基聚合制备均聚物,共聚物和嵌段共聚物的方法,其中由至少一种可自由基聚合的单体,由至少一个基团组成的引发剂组分(B)组成的单体组分(A) 引发剂,由至少一种环状多糖(衍生物)组成的多糖组分(C)和由至少一种通式(Ia)或/和(Ib)的化合物组成的调节剂组分(D)在存在下反应 水,其中R 1至R 6可各自独立地表示氢,任选取代的C 1 -C 20 烷基残基,C 3 -C 8环烷基残基,C 7 -C 34芳烷基残基或任选地 芳族C 6 -C 14烃残基和R 2和R 5可另外表示具有平均值的聚合物残基 分子量(数均)为100〜50,000道尔顿, 并且至少两个但最多四个残基R 1至R 6代表芳烃残基。 以这种方式,可以生产具有非常窄的分子量分布的聚合物。 此外,由于与现有技术相比,引发剂和调节剂的量低得多,所以聚合物仅含有非常少量的调节剂和引发剂分解产物。
