现代科学技术和国民经济的许多部门要求高分子材料应该在每一具体情况下具有所需的综合性能.然而,一般高分子化合物所存在的缺点往往限制了它的使用范围.因此,现代科学技术和生产发展的迫切需要促使高分子科学在近十年来发生了重大变革.如同冶金学上把二种不同金属配炼成优质合金,或生物学上把一种植物嫁接到另一种植物上 Many departments of modern science and technology and the national economy demand that the polymer material should have the required comprehensive properties in each specific situation.However, the shortcomings of the general polymer compounds tend to limit its scope of use.Therefore, modern science and technology And the urgent need for production development have led to a major revolution in polymer science in the last decade, as in metallurgy, blending two different metals into high-quality alloys or biologically grafting one plant onto another
