Review of the Synthesis, Characterization, and Testing of Graft Copolymers of Lignin

摘要: Lignin [8068-00-6] is a natural product produced by all woody plants. It second only to cellulose in mass of polymer formed per annum.1 constitutes between 15 and 40 percent the dry weight wood with variation lignin content being caused growing conditions, species type, parts plant tested, numerous other factors2. Plants use 1. control fluid flow, 2. add strength, 3. protect against attack microorganisms3.Each cell grows its own lignin. The undergoes “lignification” response an internally-orchestrated series reactions which take place during differentiation3. appears first primary (exterior) wall “corners”. As grows, deposits throughout then secondary, interior cell. During this growth period, develop intercellular region, also. be attached crystalline microfibrils phenylpropane linkages carboxyl groups. Such bond structure would uronic acid ester linkage.3
