Structural properties and phase behavior of crosslinked networks embedded in polymer solutions are theoretically investigated. The partial structure factor of the network is calculated using a matrix formulation of the random phase approximation and the forward scattering limit is correlated with the phase behavior. Swelling and deswelling processes are analyzed in terms of the polymer concentration, the mismatch of solvent quality with respect to polymer and network, the polymers incompatibility and their characteristic sizes. Most studies reported so far in the literature have focussed on the swelling of crosslinked networks and gels in pure solvents but the correlation of the structural properties with the phase behavior in the presence of high molecular weight polymers in solution has not been given sufficient attention. The present work is intended to fill this gap in view of the current efforts to develop novel drug encapsulating and targeted delivery devices.

聚合物溶液中交联网络的结构性质和相行为。

理论上研究了嵌入聚合物溶液中的交联网络的结构特性和相行为。使用随机相位近似的矩阵公式来计算网络的部分结构因子，并且正向散射极限与相位行为相关。根据聚合物浓度，溶剂质量相对于聚合物和网络的不匹配，聚合物的不相容性及其特征尺寸，对溶胀和溶胀过程进行了分析。迄今为止，文献中报道的大多数研究都集中在纯溶剂中交联网络和凝胶的溶胀，但是在溶液中存在高分子量聚合物的情况下，结构性能与相行为之间的相关性尚未得到足够的重视。
