摘要
通过熔融共混的方法 ,在PA6中混入 3 %～ 10 %的聚乙烯吡咯烷酮 (PVP) ,使PA6共混物的吸湿性明显提高。随PVP加入量的增大 ,PA6结晶由γ型逐渐向α型转变 ,PVP与PA6形成了分子间氢键。
By means of the melt blending of 3%～10% PVP into PA6,the moisture absorption of PA6 could be in creased obviously With the increase of the content of PVP in the blend,the PA6 crystalline state changed from γ phase to α phase,forming an intermolecular hydrogen bond between PVP and PA6 FTIR and WAXD analysis approved the existence of the intermolecular hydrogen bond and the change of the PA6 crystalline state
