共聚醚酯热塑性弹性体专利分析

Patent Analysis on the Polyether/Ester Thermoplastic Elastomers

基于专利文献检索,对共聚醚酯热塑性弹性体(TPC-ET)的国内外专利申请进行了统计和分析。结果表明:国内外公开的TPC-ET专利申请数量较少,改性技术是其研究重点。在改性和合成技术方面的布局,国内外比较近似,以改善性能的TPC-ET改性专用料的专利申请最多。国内外,TPC-ET在应用方面作为助剂也有一定的专利申请。由国内外检索专利的数量的对比可知,国内在该领域的技术起步稍晚,专利数量落后于日美等国家。

Based on the patent literature search,the patent applications of polyether/ester thermoplastic elastomers(TPC-ET)at home and abroad were analyzed statistically.The results show that there are few patent applications of TPC-ET at home and abroad,and the modification technology is the focus of its research.The layout of modification and synthesis technology is similar at home and abroad,and TPC-ET modified special material with improved performance has the most patent applications.At home and abroad,TPC-ET also has some patent applications in the application of additives.From the comparison of the number of retrieval patents at home and abroad,it can be seen that the domestic technology in this field started a little later,and the number lags behind Japan,the United States and other countries.
