Functional polymers are macromolecules to which chemically functional groups are attached;they have the potential advantages of small molecules with the same functional groups.Their usefulness is related both to the functional groups and to the nature of the polymers whose characteristic properties depend mainly on the extraordinarily large size of molecules.
The attachment of functional groups to a polymer is frequently the first step towards the preparation of a functional polymer for a specific use.However, the proper choice of the polymer is an important factor for successful application.In addition to the synthetic aliphatic and aromatic polymers, a wide range of natural polymers have also been functionalized and used as reactive materials .Inorganic polymers have also been modified with reactive functional groups and used in processes requiring severe service conditions.In principle, the reactive groups may be part of the polymer backbone or linked to a side chain as a pendant group either directly or via a spacer group. A required active functional group can be introduced onto a polymeric support chain(1) by incorporation during the synthesis of the support itself through polymerization and copolymerization of momonmers containing the desired functional groups, (2) by chemical modification of a non-functionalized performed support matrix and (3)by a combination of (1) and (2). Each of the two approaches has its own advantages and disadvantages , and one approach may be preferred for the preparation of a particular functional polymer when the other would be totally impractical. The choice between the two ways to the synthesis of functionalized polymers depends mainly on the required chemical and physical properties of the thoroughly examined in order to take full advantage of each of the preparative techniques.
Rapid progress in the utikization of functionalized polymeric materials has been noted in the recent past. Interest in the field is being enhanced due to the possibility of creating systems that combine the unuique properties of conventional active moieties and those of high molecular weight polymers.The successful utilization of these polymers are based on the physical form solvation behavior,porosity,chemical reactivity and stability of the polymers.The various types of functionalized polymers cover a broad range of chemical applications,inclding the polymeric reactants,catalysts,carriers,surfactants,stabiliz-ers,ion-exchange resins,etc.In a variety of biological and biomedical fields,such as the pharmaceutical,agriculture,food industry and the like,they have become indispensable materials,especially in controlled release formulation of drugs and agrochemicals.Besides,these polymers are extensively used as the antioxidants,flame retardants,corrosion inhibitors,flocculating agents,antistatic agents and the other technological applications.In addition,the functional polymers possess broad application prospects in the

功能性聚合物大分子的化学官能团连接；他们有潜在优势的小分子具有相同的功能组别.其效用是两个相关的功能团体和性质的聚合物,其特征特性主要取决于其超大分子.
该功能基团的聚合物通常是第一步,制备功能性聚合物为特定用途.然而,选择适当的聚合物是一个重要的因素的成功应用.除了合成脂肪族和芳香族聚合物,范围广泛的天然聚合物也被用来作为功能和反应材料.无机聚合物也被改性活性官能团和使用过程中,需要严重的服务条件.原则上,反应组的一部分可能是聚合物骨干或连接到侧链作为一个挂件组直接或通过间隔组.所需的活性官能团可以引入到聚合物支持链（1）被纳入在合成的支持本身通过聚合和共聚momonmers包含所需的官能团,（2）化学修饰的功能进行支持矩阵和（3）的组合（1）和（2）.每种方法都有自己的优点和缺点,和一个方法可能是首选的制备中的特定功能聚合物当其他完全不切实际.两国之间的选择方式,功能高分子的合成主要取决于所需的化学和物理性质的彻底检查,以充分利用各制备技术.
