研究了金屬茂催化的低分子量支化聚乙烯和線性聚乙烯的結晶及熔融行為,發現支化聚乙烯的結構與線性聚乙烯相同為正交結構,但晶格略有膨脹.支鏈的存在對熔融行為影響不大,兩種聚乙烯的熔點均隨結晶溫度的升高而非線性增加,表現出低分子量樣品的共同特徵.但支鏈的存在對結晶行為卻有很大的影響,主要是由於支鏈的存在降低了晶體的結晶速率從而影響結晶過程,使得低分子量的支化聚乙烯的結晶行為與高分子量線性聚乙烯的結晶行為相似而與低分子量的線性聚乙烯不同.動力學分析表明,低分子量的支化聚乙烯的結晶生長方式的轉變溫度比同等分子量的線性聚乙烯降低了約20Solder bar is made from high purity metal. by means of strict qualitg control the oxide and metallic and non - metallic impnrities and effectively minimized, the available high purity solder bar is with uniform and glazed surface good wetting and spreading ability after molten bright joint and minimum oxide residue after soldering. our product is suitable for wave and handwork soldering with high quality requirement
