讨论了有机硅油共混改性聚甲醛（POM）工艺过程以及共混改性材料的特性和应用。
The process of blends POM with silicone oil, its characteristics and applications were discussed.
结果表明，改性聚甲醛的分子量得到了较好的保持，抗冲击韧性及断裂伸长率均明显优于未改性聚甲醛。
The result showed the molecular weight of modified POM were kept well, which leaded higher impact strengh and elongation at break than pure POM.
聚甲醛的改性方向是提高它的刚性、耐蠕变性、润滑性，成型高精度制品。
Modified direction of POM are high modulus, creep resistant, lubrication and processing high precision products.
