高聚物非晶态的结构研究,包括玻璃态、橡胶态、粘流态、结晶高聚物中的非晶部分以及结晶熔融态的结构研究。 有关高聚物非晶态的结构,有两种不同的学术观点。Flory(1949)用统计热力学推导出“无规线团模型”(Random coil model,图1(a)),即非晶高聚物中的高分子链无论在θ溶剂中或在本体中均具有相同迴转半径的无规线团构象(服从高斯分布)。而Kargin Studies on the amorphous structure of polymers include the glassy state, rubbery state, viscous flow state, the amorphous part of the crystalline polymer and the structural study of the crystalline melting state. There are two different academic perspectives on the amorphous structure of polymers. Flory (1949) derived the “random coil model” (Figure 1 (a)) using statistical thermodynamics, in which the polymer chains in the amorphous polymer have either the? Solvent or the bulk The same radius of gyration random coil conformation (subject to Gaussian distribution). Kargin
