1 材料与方法11 合成方法:此栓塞剂采用悬浮聚合法制备。对进口水凝胶微球(hydrogelmicrospheres,HMs)合成方法加以改进,包覆10%~15%的硫酸钡作为放射示踪剂,以合成一种新型包覆硫酸钡的HMs。12 理化特性检测:①稳定性检测:取上述新型HMs03g
1 Materials and Methods 11 Synthesis: This embolic agent prepared by suspension polymerization. The synthesis method of imported hydrogel microspheres (HMs) was improved, and 10% ~ 15% barium sulfate was coated as a radiotracer to synthesize a new type of HMs coated with barium sulfate. 12 physical and chemical properties testing: ① stability test: Take the new HMs03g
