Polydicyclopentadiene (PDCPD) is a thermoset polymer that is valued in industry for its excellent mechanical properties, heat resistance, and chemical tolerance. However, the commercial polymer lacks chemically tunable functionality. Recently, a methyl ester functionalized polydicyclopentadiene (fPDCPD) was shown to offer significantly improved tunability while maintaining the same thermal stability as the unfunctionalized parent polymer. In this report, we describe the synthesis and characterization of poly[(methyl ester functionalized dicyclopentadiene)-stat-(dicyclopentadiene)] copolymers in which the mole fraction of the functionalized, ester-containing monomer, relative to the unfunctionalized dicyclopentadiene monomer, is systematically increased. Our data reveal an ability to tune physical and mechanical properties of the copolymers (e.g., alpha transition and hardness) by changing the monomer ratio and thermal curing time. Importantly, the copolymers retain the same thermal stability as the individual homopolymers, while allowing for increased control over surface energy.

官能化和非官能化的聚二环戊二烯的共聚物

聚二环戊二烯（PDCPD）是一种热固性聚合物，因其出色的机械性能，耐热性和化学耐受性而在工业上受到重视。但是，商用聚合物缺乏化学可调的功能。近来，已显示甲酯官能化的聚二环戊二烯（f PDCPD）可提供显着改善的可调性，同时保持与未官能化的母体聚合物相同的热稳定性。在本报告中，我们描述了聚[（甲酯功能化的二环戊二烯）-Stat的合成和表征-（（二环戊二烯）]共聚物，其中相对于未官能化的二环戊二烯单体，官能化的含酯单体的摩尔分数得到系统地增加。我们的数据揭示了通过改变单体比例和热固化时间来调节共聚物的物理和机械性能（例如，α转变和硬度）的能力。重要的是，该共聚物保持与各个均聚物相同的热稳定性，同时允许增加对表面能的控制。
