摘要

用简单的方法合成了聚对甲氧基苯基甲基丙烯酸酯-共甲氧基乙基甲基丙烯酸酯共聚物。以过氧化苯甲酰为引发剂，通过自由基反应聚合对甲苯基甲基丙烯酸甲酯和甲氧基甲基丙烯酸甲酯。通过傅里叶变换红外光谱（FTIR）、质子核磁共振（1H NMR）和碳核磁共振（13C NMR）等波谱技术对合成的共聚物进行了确证。采用热重分析（TGA）、衍生热重分析（导数热重分析）和差热分析（DTA）对共聚物的耐热性进行了研究。用差示扫描量热法（DSC）测定了共聚物的玻璃化转变温度（Tg）。利用扫描电镜（SEM）观察共聚物的表面织构和形貌粗糙度。所制得的共聚物具有优良的涂层性能、防腐性能和光学性能。因此，这些材料可以在太阳能、传感器、聚合物导电性、电池电解质、纳米技术、粘度和生物医学等不同方面得到利用。

Synthesis and characterization of thermal properties of poly(p-cumylphenyl methacrylate-co-methoxyethyl methacrylate) copolymers

The poly(p-cumylphenyl methacrylate-co-methoxyethyl methacrylate) copolymers has been fabricated in a simple way. The p-cumylphenyl methacrylate and methoxy methacrylate were polymerized by free radical mechanism using benzoyl peroxide as an initiator. The synthesized copolymers were confirmed by Fourier transform infrared spectroscopy (FTIR), proton nuclear magnetic resonance (¹H NMR) and carbon nuclear magnetic resonance (¹³C NMR) spectral techniques. The heat durability of copolymers has been investigated by Thermogravimetric analysis (TGA), derivative thermogravimetry, and differential thermal analysis (DTA). The glass transition temperature (Tg) of copolymer was carried out using differential scanning calorimetry (DSC). The scanning electron microscopy (SEM) was utilized to observe the surface texture and morphology roughness of copolymers. The obtained copolymers have possess an excellent coating property, anti-corrosive property, and optical property. Hence, these can be utilize in different way like solar, sensors, polymer conductivity, battery electrolytes, nanotechnology, viscosity, and biomedical.

期刊介绍： The Journal of Molecular Structure is dedicated to the publication of full-length articles and review papers, providing important new structural information on all types of chemical species including: • Stable and unstable molecules in all types of environments (vapour, molecular beam, liquid, solution, liquid crystal, solid state, matrix-isolated, surface-absorbed etc.) • Chemical intermediates • Molecules in excited states • Biological molecules • Polymers. The methods used may include any combination of spectroscopic and non-spectroscopic techniques, for example: • Infrared spectroscopy (mid, far, near) • Raman spectroscopy and non-linear Raman methods (CARS, etc.) • Electronic absorption spectroscopy • Optical rotatory dispersion and circular dichroism • Fluorescence and phosphorescence techniques • Electron spectroscopies (PES, XPS), EXAFS, etc. • Microwave spectroscopy • Electron diffraction • NMR and ESR spectroscopies • Mössbauer spectroscopy • X-ray crystallography • Charge Density Analyses • Computational Studies (supplementing experimental methods) We encourage publications combining theoretical and experimental approaches. The structural insights gained by the studies should be correlated with the properties, activity and/ or reactivity of the molecule under investigation and the relevance of this molecule and its implications should be discussed.
