用广角x射线散射研究了聚甲基丙烯酸乙酯的局部温度依赖结构。这些结果与最近的广角中子散射结果以及对该聚合物动力学的大量研究结果相结合。广角x射线结果的温度依赖性指出了局部序的发展，这是由中子散射结果支持的，并且与弛豫动力学T(g)和T(c)的特征温度有关。聚甲基丙烯酸乙酯主要是在同规和等规状态下进行研究，在x射线结果中显示出截然不同的局部结构。
The local, temperature dependent structure of poly-(ethylmethacrylate) was studied with wide-angle x-ray scattering. The results were set into context to recent wide-angle neutron scattering results as well as to the results from a multitude of studies of the dynamics of this polymer. The temperature dependence of the wide angle x-ray results point to the development of local order which is backed by the neutron scattering results and which is connected to characteristic temperatures of the relaxation dynamic T(g) and T(c). The poly-(ethylmethacrylate) was studied in its predominantly syndiotactic as well as predominantly isotactic state displaying vastly different local structures as manifested in the x-ray results.
