  Tailored star-shaped statistical teroligomers viaATRP for lithographic applications

  摘要：

  通过先核后原子转移自由基聚合（ATRP）方法，制备了一系列由糖核酸核心和臂组成的五角星状三聚体，其中臂由α-γ-丁内酯甲基丙烯酸酯（GBLMA）、甲基金刚烷基甲基丙烯酸酯（MAMA）和羟基金刚烷基甲基丙烯酸酯（HAMA）组成，臂长和臂数是确定的。糖核酸核心通过ATRP起始位点和非反应位点进行修饰，从而能够合成具有较小臂数但相同核心的星状聚合物。星状三聚体具有窄分子量分布和低多分散性指数（PDI < 1.1），仅在Xp > 50%的高转化率下才会出现可忽略的副反应。没有副反应且精确达到目标分子量表明对反应的控制非常出色。首次将选定的星状三聚体作为光刻胶材料进行了研究。通过组合方法优化了光刻工艺的精细条件。所观察到的图案具有低线边和线宽粗糙度，这表明星状结构在此应用中具有潜力。

  The invention relates to a polymer comprising 50-100% by weight, with regard to the weight of the polymers, of repeating units, which are derived from one or more ethylenically unsaturated ester compounds of formula (I), in which R represents hydrogen or methyl; R 1 represents a linear or unbranched alkyl radical with 7 to 30 carbon atoms, and; R 2 and R 3 independently represent hydrogen or a group of formula —COOR′, wherein R′ represents hydrogen or an alkyl group with 7 to 30 carbon atoms. The polymer is a star polymer with 3 to 21 arms and at least 3 of the arms consist of at least 40% by weight, with regard to the weight of the arms, of repeating units, which are derived from one or more ethylenically unsaturated ester compounds of formula (I), in which R 1 represents a linear or unbranched alkyl radical with 7 to 30 carbon atoms, and; R 2 and R 3 independently represent hydrogen or a group of formula —COOR′, wherein R′ represents hydrogen or an alkyl group with 7 to 30 carbon atoms. The invention also relates to oil formulations comprising the inventive polymers. The inventive polymers having a high thickening action can be used, in particular, as viscosity modifiers, pour point depressants, dispersing agents and/or friction modifiers.
