日本研发出超耐热胶粘剂日本广岛大学和积水化学工业公司日前通过稀土金属配位催化剂,采用活性聚合方法研制出丙烯酸系列新型胶粘剂。据外电介绍,这种丙烯基嵌段聚合物胶粘剂比过去的自由基引发聚合法所得的无规胶粘剂在耐热性、低温性能和耐剥离性等方面优越得多。同时,分子量分布范围很窄,可耐200℃以上高温。
Japan developed a heat-resistant adhesive Japan Hiroshima University and Sekisui Chemical Industry Company recently through the rare earth metal coordination catalyst, the use of living polymerization method developed a new series of acrylic adhesives. According to foreign reports, the propylene-based block polymer adhesive than the past free radical polymerization initiator obtained by the random adhesive in the heat resistance, low temperature performance and peel resistance and so much more. At the same time, the molecular weight distribution of a narrow range, can withstand high temperatures above 200 ℃.
