Deuterated-tritiated polymers are a type of promising target materials for inertial confinement fusion (ICF). The preparation of a deuterated-tritiated polymer was performed from a deuterated polybutadiene under tritium through solid state catalytic tritiation with 5 wt% Pd/BaSO₄ as a catalyst. After reaction, the gas mixture in the vessel and the raw T₂/Ar mixture in the flask were analyzed with a gas chromatography, a quadrupole mass spectrometer and a high resolution gas analysis mass spectrometer. The ²H-NMR and ³H-NMR spectra were employed to characterize the deuterated-tritiated polymer. Both isotopic exchange and addition during the reaction were confirmed and the tritium ratio of the deuterated-tritiated polymer was determined to be 26.5 %.The solid state tritiation free of solvents can avoid the generation of high radioactive liquids.

氘代polymers代聚合物是用于惯性约束聚变（ICF）的一种有前途的目标材料。氘化-代聚合物的制备是在氘气中，通过氘化聚丁二烯，以5 wt％Pd / BaSO ₄作为催化剂进行固态催化tri化。反应后，用气相色谱仪，四极质谱仪和高分辨率气体分析质谱仪分析容器中的气体混合物和烧瓶中的粗T ₂ / Ar混合物。所述² H-NMR和³1 H-NMR谱用于表征氘代ti化的聚合物。确认了反应过程中的同位素交换和添加，氘化-代聚合物的the比确定为26.5％。不含溶剂的固态tri化可避免高放射性液体的产生。
