摘要
选择Ｓｉ－Ｃ伸展振动和ＣＨ３平面摇摆震动在～８５５ｃｍ－１及～８００ｃｍ－１处的吸收峰作为分析峰，采用红外光谱分析法对ＳＹＺ—２医用级硅橡胶残存单体及低聚物含量作了测定，未检出残存单体及低聚物。
The silicone rubber SYZ - 2 was used as the assistant material of the female long - acting contraceptive subdermal implant as well as plastic saddle nose. The quality of SYZ - 2 must be controlled strictly because it is a biomaterial covered in human body for long time. Selected absorption peak at 855 cm -1 and 800 cm -1 as analysis peak, the residues of the monomer and oligomer in SYZ - 2 were detected by IR analysis.
