一、分子设计的意义高分子科学从H.Staudinger提出链结构概念以来,仅有五十年的历史,但已显示出强大的生命力。高分子材料主要包括塑料、橡胶、纤维等,年产能力已达一亿三千万吨以上。合成橡胶的产量已二倍于天然橡胶,而合成纤维与化学纤维的产量合起来才等于天然纤 First, the significance of molecular design Polymer science from the H.Staudinger proposed chain structure concept, only 50 years of history, but has shown great vitality. Polymer materials, including plastics, rubber, fiber, etc., with an annual output capacity of more than 130 million tons. Synthetic rubber production has twice the natural rubber, and synthetic fiber and chemical fiber production together is equal to the natural fiber
