阐明高分子链的缠结概念,介绍互穿高分子结构及其特性,举出二个例子说明这种概念适用于离子交换树脂的合成:(1)用于合成从发酵液中提取链霉素的不溶胀性羧酸离子交换树脂,(2)用于减少离子交换树脂中交联剂二乙烯苯用量从7～10％到1％,而不增加水中溶胀度。
To elucidate the concept of entanglement in polymer chains and to introduce interpenetrating polymer structures and their properties, two examples are given to illustrate that this concept is applicable to the synthesis of ion exchange resins: (1) for the synthesis of streptomycin from fermentation broth (2) is used to reduce the amount of divinylbenzene used as a cross-linking agent in the ion exchange resin from 7 to 10% to 1% without increasing the degree of swelling in water.
