Based on results of small and wide angle X-ray scattering measurements, we report a new microstructural feature in bottlebrush poly (n-alkyl methacrylate)s larger than side chain packing. Temperature dependent X-ray experiments confirmed that such large scale aggregation structure is originated from the crystallization of the side chains. Two-dimensional X-ray scattering patterns revealed that the structure is due to the formation of disordered regions locate on average two layers of well crystallized side chains apart. Crystallization of the side chains rejected backbone entanglements to the surrounding area forming regions of high entanglement density so that restricting the crystallization of side chains. As such a density contrast is created between the crystallized regions and the disordered ones which results in strong small angle X-ray scattering signals.

根据小角度和广角X射线散射测量的结果，我们报告了大于侧链填料的聚脂（甲基丙烯酸正烷基酯）洗瓶刷的新微结构特征。与温度有关的X射线实验证实，这种大规模的聚集结构源自侧链的结晶。二维X射线散射图表明，该结构是由于无序区域的形成所致，该区域位于平均两层结晶良好的侧链之间。侧链的结晶拒绝骨架缠结到周围区域，形成高缠结密度的区域，从而限制了侧链的结晶。
