无水AlCl3催化PVC/PS反应性增容的研究
以无水AlCl3为催化剂,通过聚氯乙烯（PVC）与聚苯乙烯 (PS) 之间Friedel-Crafts反应,实现了PVC/PS共混体系的反应性增容,使PVC与PS熔融共混温度由160℃降为140℃；通过预碾磨和加入苯乙烯 (St)的方法,提高材料韧性,成功制备综合力学性能良好的PVC/PS合金材料.应用FTIR、DSC、SEM和力学性能测试等手段表征了合金材料的结构与性能.结果表明:FTIR出现了1943cm-1,838 cm-1两个苯环对位被取代的特征吸收峰;DSC在89℃出...

微波辐照实现PVC-PS之间的Friedel-Crafts接枝反应
在四氢呋喃、环己酮等溶液中实现了聚氯乙烯 (PVC)与聚苯乙烯 (PS)的Friedel-Crafts接枝反应，考察了加热方式、反应温度、催化剂种类、催化剂用量对接枝反应的影响，通过FT-IR表征了PVC-g-PS接枝物的结构，探讨了反应的机理和特点。研究发现：油浴加热和微波辐照都能使PVC和PS发生接枝反应，但微波辐照效果更好，油浴加热，接枝率仅0.27%，而微波辐照接枝率高达23%；油浴加热时产物少且多为间位，微波辐照时产物...

10.【RSC Adv.】Aggregation behavior of the blends of PS-b-PEO-b-PS and PS-b-PMMA at the air/water interface.
In order to explore the aggregation mechanisms of mixed polymeric Langmuir monolayers and enrich the structures of their corresponding Langmuir–Blodgett (LB) films, a predominantly hydrophilic triblock copolymer polystyrene-block-poly(ethylene oxide)-block-polystyrene (SEOS69K, Mn = 69?000, 43.5 wt% PEO) was mixed with an amphiphilic diblock copolymer polystyrene-block-poly(methyl methacrylate)...

THE COMPLETE BRITTLE-DUCTILE TRANSITION OF THE BINARY AND TERNARY PS BLENDS
关键字： Polystyrene, Brittle-Ductile Transition, Blends, PS/SBS, and PS/SBS/CaCO3
The known brittle-ductile transition (BDT) theories of polymers were studied only in a single aspect or from a single viewpoint. However, the change in structure of modified materials will be responded by the properties in se...
