聚丙烯釜内合金专利分析

摘要

The progress and technology field of Chinese patents in polypropylene catalyzed alloys were searched and analyzed at home and abroad from 1988 to 2009. The results showed that a certsin foundation was laid for the domestic polypropylene in- reactor alloys technology had a base, but compared with the largest foreign companies, there still had a long way to go in advanced technology content and technology depth.%通过对聚丙烯釜内合金中国专利技术的检索和分析,研究了国内外公司从1988-2009年相关的聚丙烯釜内合金专利的进展情况、技术领域等.结果表明,国内聚丙烯釜内合金的研发技术已经具备一定的基础;但与国外大公司相比仍有差距,先进技术含量不高,研究不够深入.
