对聚合物迁移行为的研究目前十分引人关注,因为其在生物医学设备保护涂层(如涂料和清漆)、食品和蔬菜包装材料,以及超过滤、电渗析和渗透蒸发工艺等领域非常重要。就聚合物共混体而言,迁移行为主要取决于其成分、组分聚合物间的相容性以及形态。据Mathew等人的报道,在NR/PS共混物扩散试验中使用芳香烃(如苯、甲苯、二甲苯)作为溶剂时,增加交联密度能够将溶剂吸收量减少40%。Kumnuantip和Sombatsompop阐述了甲苯在NR/(再生胶)RR共聚物中作为渗透剂的溶胀行
Research into the migration behavior of polymers is of great interest at the moment because of its importance in biomedical device protective coatings such as coatings and varnishes, food and vegetable packaging materials, and ultrafiltration, electrodialysis and pervaporation processes. In the case of polymer blends, the migration behavior depends mainly on its composition, compatibility between the constituent polymers, and morphology. According to Mathew et al., The use of aromatic hydrocarbons (such as benzene, toluene, xylene) as the solvent in the diffusion test of NR / PS blends increases the crosslinking density and can reduce the solvent uptake by 40%. Kumnuantip and Sombatsompop describe the swelling behavior of toluene as a penetrant in NR / (reclaimed rubber) RR copolymers
