Polymer degradation — is a change in the properties tensile strength, colour, shape, etc of a polymer or polymer based product under the influence of one or more environmental factors such as heat, light or chemicals. These changes are usually undesirable, such as… … Wikipedia
Polymer — Appearance of real linear polymer chains as recorded using an atomic force microscope on surface under liquid medium. Chain contour length for this polymer is 204 nm; thickness is 0.4 nm.[1] A polymer is a large molecule (macromolecule … Wikipedia
UV degradation — Many natural and synthetic polymers are attacked by ultra violet radiation and products made using these materials may crack or disintegrate. The problem is known as UV degradation , and is a common problem in products exposed to sunlight.… … Wikipedia
Thermal degradation of polymers — is molecular deterioration as a result of overheating. At high temperatures the components of the long chain backbone of the polymer can begin to separate (molecular scission) and react with one another to change the properties of the polymer.… … Wikipedia
