【摘要】：極性單體是指帶有極性基團(tuán)的烯烴類(lèi)單體,主要包括含鹵素類(lèi)極性單體、含氧類(lèi)極性單體、含氮類(lèi)極性單體和含磷類(lèi)極性單體。其中帶有乙烯基且與所帶極性基團(tuán)相共軛的極性單體稱(chēng)為極性乙烯基單體,如甲基丙烯酸甲酯、2-乙烯基吡啶和乙烯基磷酸酯等。這類(lèi)單體所形成的極性乙烯基聚合物是極性基團(tuán)作為側(cè)鏈的烯烴聚合物,該類(lèi)化合物在黏性、韌性、界面性質(zhì)(染色性和印刷性)、與溶劑或其他聚合物的相容性方面較傳統(tǒng)非極性聚烯烴材料有明顯的優(yōu)勢(shì)。為了使聚合物具有好的物理性能,獲得具有一定規(guī)整度的聚合物是近年來(lái)研究的熱點(diǎn)。聚合物的立體結(jié)構(gòu)對(duì)其本身的物理性能有著顯著的影響,如熔點(diǎn)、玻璃化轉(zhuǎn)變溫度和機(jī)械性能等。獲取立構(gòu)規(guī)整性聚合物的最有效方式是發(fā)展催化聚合反應(yīng)的立體選擇性催化劑。本文綜述了近幾年極性乙烯基單體立體選擇性聚合催化劑的研究進(jìn)展,這里所涉及的極性乙烯基單體包括:丙烯酸酯類(lèi)、丙烯酸酰胺、乙烯基磷酸酯、乙烯基吡啶和雜原子取代苯乙烯單體。所涉及的聚合體系是配位聚合、路易斯酸堿對(duì)和陰離子聚合體系。
[Abstract]:Polar monomer refers to olefine monomer with polar group, which mainly includes halogen polar monomer, oxygen polar monomer, nitrogen polar monomer and phosphorus polar monomer. The polar monomers with vinyl groups and conjugated with polar groups are called polar vinyl monomers, such as methyl methacrylate, 2-vinylpyridine and vinyl phosphate. Polar vinyl polymers formed by this kind of monomers are olefine polymers with polar groups as side chains. These compounds have obvious advantages over traditional non-polar polyolefine materials in viscosity, toughness, interfacial properties (dyeing and printing) and compatibility with solvents or other polymers. In order to make polymers have good physical properties, it is a hot research topic in recent years to obtain polymers with certain regularity. The three-dimensional structure of the polymer has a significant effect on its own physical properties, such as melting point, glass transition temperature and mechanical properties. The most effective way to obtain vertical structured polymers is to develop stereoselective catalysts for catalytic polymerization. In this paper, the research progress of polar vinyl monomer stereoselective polymerization catalysts in recent years is reviewed. The polar vinyl monomers involved include acrylic esters, acrylic amides, vinyl phosphate, vinylpyridine and hetero-atom substituted styrene monomers. The polymerization system involved is coordination polymerization, Lewis acid-base pair and anion polymerization system.
