Characterization of Polymer Blends Using UV-Visible Spectroscopy [Pg.789]

Polymers are constructed from monomers (molecules capable of bonding in long chains) that are linked by chemical bonds they are produced by the process of polymerization (the linking up of monomers) and may occur either naturally or synthetically. [Pg.789]

A polymer blend is a macroscopically homogeneous mixture of two or more different species of polymer [1], The number of polymeric components that comprise a blend is often designated by an adjective such as binary, ternary or quaternary. The manufacture of polymer blends has opened an exciting new direction for modification of the structure and physical properties of these materials, while extensive academic research and commercial interest have together led to the development of many applications for these materials.

Morphologically, most polymer blends are semi rystalline [9,10] as they are mixtures of small crystals and amorphous materials. Semi-crystalline polymers are composed of both amorphous and crystalline regions the amorphous structure is mainly characterized by entanglements, which are physical nodal points between molecular chains. Semi-crystalline polymers are characterized (beside the [Pg.789]
