瑞士勃兰德公司研制成功一种既防水又溶于水的塑料包装容器。它具有一般塑料包装容器的各种性能,并且能防水,但在需要时,又可用不同的方法溶于水。这种用于包装的既防水又溶于水的塑料,是先将惰性的、带有水溶性反应基的单体聚合,进而共聚,得到一种不溶于水的聚合物;然后,用一 Swiss Brand has successfully developed a waterproof and water-soluble plastic packaging containers. It has the general properties of plastic packaging containers, and can be waterproof, but when needed, they can be dissolved in water in different ways. This water-resistant and water-soluble plastic for packaging is obtained by first polymerizing an inert, water-soluble reactive group-containing monomer and then copolymerizing to obtain a water-insoluble polymer;
