天津师范大学硕士学位论文中文摘要功能高分子材料化学是目前发展迅速,在材料科学中占有重要地位的新兴学科。功能高分子材料的研究与应用是当前世界化学工业发展的重要趋势,作为功能高分子材料之一的高分子化学试剂不仅具有很高的活性和选择性,而且具有普通试剂所不具有的许多特点,比如可以简化操作过程,提高试剂的稳定性和安全性,特别是可以满足环保和节能的需要。在本论文中,合成了一种新型的具有优良选择性的氧化剂一聚()铬载体氧化剂,使用这种氧化剂可以把醇类化合物和卤代烃类化合物氧化成醛。对反应中间体4一乙烯基吡啶和聚(4一乙烯基吡啶)合成的影响因素进行了讨论,并利用红外光谱、元素分析、1HNMR和MS等现代物理分析方法对产物的结构进行了表征。本论文所作的工作如下: 。 ,并对反应的影响因素进行了探讨。 ,(PVP)。 ,并且合成了聚合物载体(Q)氧化剂。关键词: ,悬浮聚合,聚4一乙烯基吡啶(PVP)树脂, 功能高分子,聚4-乙烯基吡啶(cr)氧化剂。天津师范大学硕士论文 Abstract Functional polymer was anew important subject inmaterials anddeveloping study andapplication offunctional polymer materials isthesignificant trend inthedevelopment ofchemistry industry polymer reagent as one kind offunctional polymer materials not only hashigIl active and selective functions,but also hasmany characteristics mon reagent do nothold,such aspredigesting manipulation,improving thestabilizationandsafety ofreagent,and achieving thepurpose ofenvironmental protection andeconomy on energy especially. Inthispaper'A new selectivepoly(4-vinylpyridine)chromium oxidant was synthesized,and byusing theoxidant,the alcohol and halo—pounds can beoxidized toaldehyde,and some intermediates such as4-vinylpyridine andpoly (4-vinylpyridine)have been synthesized,and some factors inthe synthesis were discussed,and the structure pounds inthispaper were characterized not only by IRspectraand element analysis,but alsoby1HNMR andMS. The primaryjobs of thispaper are asfollows: development andapplication of functional polymer materials were reviewed and thesignificance ofthispaper was reviewed was summarized. -vinylpyridine was synthesized and characterized and thefactors ofthe synthesis were studied. application oftheCROSS—linkedpoly(4-vinylpyridine)resin(PVP)was reviewed and thecross—linkedpoly(4-vinylpyridine)resin was synthesized andcharacterized. characteristic oftheoxidizing polymer
