Polydicyclopentadiene (PDCPD) is a tough, heavily crosslinked thermoset polymer that has high heat, chemical, and impact resistance coupled with a low density. Current limitations to the broader industrial application of PDCPD include its low surface energy and lack of chemical tunability. Here, we report the first example of a polymer derived from a carboxyl-functionalized dicyclopentadiene monomer and its subsequent thermal crosslinking. The resulting material has the highest glass-transition temperature reported for a polydicyclopentadiene and allows for the facile manipulation of the surface chemistry through alteration of the embedded functional group. We also report the first observation by differential scanning calorimetry of the crosslinking step as a discreet thermal event.

具有高T g和可调表面能的热交联功能化聚二环戊二烯

聚二环戊二烯(PDCPD)是一种坚韧的,高度交联的热固性聚合物,具有高的耐热性,耐化学性和耐冲击性以及低密度。PDCPD在更广泛的工业应用中的当前限制包括其低表面能和缺乏化学可调性。在这里,我们报道了衍生自羧基官能化的二环戊二烯单体及其后续热交联的聚合物的第一个例子。所得材料具有聚二环戊二烯报道的最高玻璃化转变温度,并且可以通过改变嵌入的官能团轻松地控制表面化学性质。我们还报告了通过差示扫描量热法对交联步骤的第一个观察结果,这是一个离散的热事件。
