摘要:
以环氧大豆油(ESO)和丙烯酸为原料、三苯基膦为催化剂,合成了环氧大豆油单丙烯酸酯(AESO); 其次,通过大单体自由基聚合合成了聚甲基丙烯酸甲酯接枝环氧大豆油共聚物。通过FT-IR、1H NMR、GPC、DSC、TGA、拉伸和冲击性能测试分析了共聚物的结构和性能。结果显示:成功制备了聚甲基丙烯酸甲酯-co-环氧大豆油接枝共聚物,发现环氧大豆油对聚甲基丙烯酸甲酯(PMMA)有较好的增韧作用; 随着AESO的引入,改性后PMMA的冲击强度、拉伸强度、断裂伸长率都得到了明显的提高,其中,冲击强度最大提高了3倍左右,这主要是由于环氧大豆油的引入可以明显的降低共聚物的玻璃化转变温度。另外,共聚物较纯PMMA的热稳定性得到提高。
Abstract:
Epoxidized soybean oil mono-acrylate(AESO)was synthesized by ring opening reaction of ESO with acrylic acid using triphenylphosphine as a catalyst, and hydroquinone as a inhibitor. Poly(methyl methacrylate)-co-epoxidized soybean oil graft copolymers were synthesized through macromonomer free radical polymerization. The structure and properties of copolymers were characterized by Fourier Transform Infrared Spectroscopy(FT-IR), 1H Nuclear Magnetic Resonance(1H NMR), Gel Permeation Chromatography(GPC), Differential Scanning Calorimetry(DSC), Thermo Gravimetric Analyzer(TGA), tensile and impact property tests. Results showed that the epoxidized soybean oil mono-acrylate, and poly(methyl methacrylate)-co-epoxidized soybean oil graft copolymers were successfully synthesized. It was found that epoxidized soybean oil had good toughening effect on PMMA. With the addition of AESO, the impact strength, tensile strength and elongation at break of PMMA graft copolymers were greatly improved by epoxidized soybean oil side chain, and the highest impact strength of the copolymer was about 3 times of that of PMMA homopolymer. The improvements are mainly due to that epoxidized soybean oil side chain can significantly reduce the glass transition temperature of copolymers. Furthermore, PMMA-co-ESO showed better thermal stability than that of pure PMMA.
