By combining poly(1,4-isoprene) (PI) with poly(ferrocenylmethyl methacrylate) (PFMMA) in a diblock copolymer structure by means of anionic polymerization we obtained narrowly dispersed PI-b-PFMMA copolymers with molecular weight ranging from 13000 to 62000 g/mol. The products were stable up to 228 °C, according to thermal gravimetry, which allowed us to further investigate their viscoelastic and X-ray scattering properties at elevated temperature by rheology and SAXS, respectively. For PI-b-PFMMA with total molecular weight 13400 g/mol a phase transition at 105 °C was identified leading to the segmental mixing at T > 105 °C and microphase separation at T < 105 °C. The microphase separated morphology acquired hexahonally packed cylinder (HEX) microstructure in bulk. The explanation of the ordered HEX morphology was derived from a quantification of the thermodynamic immiscibility between PI and PFMMA segments via random phase approximation theory yielding generally accepted dependency of the Flory-Huggins interaction parameter (χ) on temperature.

通过阴离子聚合将聚（1,4-异戊二烯）（PI）与聚（二甲基二茂铁基甲基丙烯酸酯）（PFMMA）结合在二嵌段共聚物结构中，我们获得了分子量为13000至62000的窄分散的PI- b -PFMMA共聚物克/摩尔 根据热重量分析法，该产品在高达228°C的温度下稳定，这使我们能够分别通过流变学和SAXS进一步研究其在高温下的粘弹性和X射线散射特性。对于总分子量为13400 g / mol的PI- b -PFMMA，确定在105°C发生相变，从而导致在T  > 105°C时发生分段混合，并在T发生微相分离。 <105°C。微相分离的形态获得了六方堆积圆柱（HEX）的微观结构。有序的HEX形态的解释来自PI和PFMMA链段之间热力学不混溶的定量化，方法是通过随机相近似理论得出的，通常认为Flory-Huggins相互作用参数（χ）对温度具有依赖性。
