groups from the polymer backbone, as confirmed by differential scanning calorimetry. The potential for the utilization of this polymer as a thermally removable adhesive was demonstrated by a simple adhesion test. This method provides access to thermally cleavable epoxy networks that can be quickly and irreversibly disintegrated into nonvolatile components upon heating to a specified temperature. © 2013

降冰片烯基团连接到主骨架上。聚合物是通过适当的双环二烯单体的自由基1,4-聚合反应合成的。生成的聚合物可以在二胺存在下进行交联,并通过在160°C下进行热处理进行去交联,这会引起Diels-Alder逆反应并从聚合物主链上裂解悬垂基团,这已通过差示扫描量热法得到了证实。通过简单的粘合试验证明了将该聚合物用作热可移除粘合剂的潜力。这种方法提供了可热裂解的环氧网络的途径,当加热到指定温度时,该网络可迅速不可逆地分解成非挥发性组分。©2013 Wiley Periodicals,Inc. J. Polym。科学,A部分:Polym。
