比较了尼龙 6 /线型低密度聚乙烯 (PA6 /L L DPE)和尼龙 10 10 /线型低密度聚乙烯 (PA10 10 /L L DPE)共混物的织构形态。共混物的织构形态除与织构调节剂、组分比有关外 ,还与尼龙的结构有很大关系。在尼龙 /聚乙烯二元共混物中 ,分散相粒子以球状 (或椭球状 )形式存在 ,粒子较大 ,两相界面清晰。加入织构调节剂后 ,分散相粒子明显变小 ,分布均匀 ,在尼龙 6共混物中 ,除仍有表面光滑的球状粒子外 ,出现了莲藕断面状粒子 ,但两相之间仍有缝隙 ,而在尼龙 10 10共混物中 ,出现了辐 (车 )轮状粒子 ,两相间相互作用强 ,分散相粒子与连续相之间紧紧地连接在一起 ,表明高碳数的尼龙 10 10与聚乙烯的链段间的相容性更好 The textures of blends of nylon 6 / linear low density polyethylene (PA6 / L LDPE) and nylon 10 10 / linear low density polyethylene (PA10 10 / L LDPE) were compared. In addition to the texture of blends and texture control agent, composition ratio related, but also with the nylon structure has a great relationship. In nylon / polyethylene binary blends, the disperse phase particles exist in the form of spheres (or ellipsoids), the particles are large, and the interface between the two phases is clear. With the addition of the texturizing agent, the disperse phase particles became smaller and distributed evenly. In the nylon 6 blend, apart from the spherical particles with smooth surface, the cross-shaped particles of lotus root appeared, but there were still gaps between the two phases , While in the nylon 10 10 blends, the spoke (car) wheel-shaped particles appeared and the interaction between the two phases was strong. The dispersed phase particles were closely connected with the continuous phase, indicating that the high carbon number nylon 10 10 Compatibility with segments of polyethylene is better
