从专利角度看丁基橡胶生产技术的发展趋势

Developmental Trend in Butyl Rubber Technology from the Patent Viewpoint

专利文献记载了技术发展的最新成果,是开展相关领域技术发展态势分析的重要根据。对丁基橡胶全球专利信息进行了收集与分析,结果表明,该领域技术研发活动持续增强,专利保护网已基本形成,丁基橡胶技术市场主要在建有丁基橡胶装置的国家,产品市场主要在亚洲,这些地区分别是生产技术和应用技术专利布局的重点;近年研发热点和专利保护重点主要是功能化改性技术和催化体系;国外跨国公司专利技术优势明显,埃克森和朗盛公司是丁基橡胶技术的主要垄断者,他们在研发、专利战略和策略方面各有特点,值得中国企业借鉴。

In this paper, the global patent information of butyl rubber（IIR） is collected and analyzed. The results show that the technical R ＆ D activities in this field have continued to be strengthened, and the patent protection network has largely been formed already. The IIR technology markets are mainly located in the countries where IIR plants are established, and the product markets are mainly located in Asia. These regions are the pivots in the patent layout of the production technology and applied technology. In recent years, the R ＆ D hot points and patent protection focal points mainly lie in functional modification technology and the catalytic system. The foreign and transnational companies have evident advantages in the patent technologies. Exxon Company and Lanxess Company are the key monopolist in the IIR technology, and they have many features in the R ＆ D, patent strategy and tactic aspects.
