摘　　要：杜仲胶由于易结晶,长期以来只能作塑料用。杜仲胶硫化高弹性橡胶的成功,使这一材料的研究开发进入新阶段。几年来,中科院化学所杜仲胶组以探索杜仲胶硫化过程机理为中心开展了基础研究及资源综合利用开发。从理论上发现了杜仲胶硫化过程三阶段,杜仲胶的“橡-塑”二重性及其临界转变的定量规律;以三阶段材料为基础提出了“杜仲胶材料工程学”的设想;提出了橡-塑统一材料谱概念,并根据杜仲胶在此材料谱中位置,用过渡性观点解释了它的硫化过程三阶段及其“橡-塑”二重性在应用开发方面,以三阶段材料为基础,形成了系列专利技术。在上述工作带动下,杜仲资源的综合开发,已形成了以杜仲胶为中心的,包括医药、饮料、各类功能材料的系列开发工程。为橡胶工业提供后备战略资源的杜仲胶开发,前景光明。Gutta-Percha has been used only as plastics for a long time because of its crystallinity. The birth of highly elastic vulcanizate of Gutta-Percha means that the research and development of Gutta-Percha have entered a new stage. The vulcanizing process of Gutta-Percha and its comprehensive utilization have been studied systematically by us. The three-stage character of its vulcanizing process, and the duality of plasticity and elasticity and the quantitative rule of its crystal transition have been discovered. We have proposed the concept of 'the unitary materials-graph composed of rubbers and plastics' and explained the three-stage character and its duality of plasticity and elasticity by using the transitional viewpoint on the basis of the place of Gutta-Percha in the materials-graph. As regards its application 1 we have registered a series of patents. A two-stage developing project for the comprehensive utilization of Gutta-Percha resource has been proposed by us. Its development prospect is very bright.
