【摘要】 选择弹性体、酯类、醇类三种不同的增韧剂 ,采用共混挤出法 ,制备柔韧性石油发酵尼龙 12 12。研究了不同增韧剂、不同加入量对柔韧性石油发酵尼龙 12 12的力学性能的影响 ,试验发现 ,当增塑剂B、C的质量分数为 8%～ 10 %时 ,增韧效果最好更多还原

【Abstract】 s Three kinds of different plasticizers,such as elastomer,ester and alcohol,were used in the preparation of flexible and tough PFPA1212 by means of blending extrusion.The effects of different plasticizer and its content on the mechanical properties of the prepared PFPA1212 were studied.The results showed when the mass fraction of plasticizer B and C was 8%～10%,the toughening effect was the best.更多还原
