摘要
将少量（１％）自制的甲基丙烯酸十八醇酯（ＳＭＡ）与丙烯酰胺（ＡＭ）共聚物Ｐ（ＳＭＡ－ＡＭ）添加到聚丙烯（ＰＰ）中进行共混，能大幅度提高聚丙烯的亲水性和粘合强度。Ｐ（ＳＭＡ－ＡＭ）的加入，改善了ＰＰ的流变性能，对ＰＰ的结晶度和拉伸强度影响不大。俄歇电子能谱（ＡＥＳ）分析表明，Ｐ（ＳＭＡ－ＡＭ）在ＰＰ共混物表面富集。
Blending polyproperene(PP)with small content copolymers of octodecyl methacrylate and acrylamide[P(SMA-AM)],which had been synthesized by ourselfs can decrease the hydrophilicity of PP surface and improve adhesion strength.Addition P(SMA-AM) to PP improved the rheological properties and had a little influence on the PP crystallinity and tensile strength.AES analysis of PP blend shows that copolymer P(SMA-AM) is rich on the PP surface.
