| 摘 要： | 采用原子转移自由基聚合(ATRP)法合成了一系列新的三嵌段共聚物大分子偶联剂聚苯乙烯-b-聚甲基丙烯酸十四酯-b-聚3-甲基丙烯酰氧基丙基三甲氧基硅烷(PSTK),通过凝胶渗透色谱(GPC)、红外光谱(FT-IR)和核磁共振(1H-NMR)证实了其结构,并研究了其对玻璃纤维/聚丙烯复合材料力学性能的影响。结果表明:采用大分子偶联剂处理玻璃纤维可使玻纤毡/聚丙烯复合材料冲击强度和弯曲模量都得到很大程度的提高。

| Abstract: | A series of tri-block copolymers of styrene/ tetradecyl methyl acrylate/ 3-methacryloxyl-propyl thimethoxyl silane(PSTK) was synthesized by atom transfer radical polymerization(ATRP).The structures of those copolymers were characterized by means of gel permeation chromatography(GPC),(infrared) spectrum(IR),and nuclear magnetic resonance(()~1H-NMR).Effect of tri-block copolymers on the mechanical properties of glass fiber/polypropylene composites was also investigated.The results show that impact strength and flexural modulus of glass fiber/ polypropylene increase greatly using the copolymer coupling. |

| Keywords: | ATRP copolymer coupling PSTK tri-block copolymers |
