ADORE

Koordinierung des Intermedi?rstoffwechselsMacromolecular modifiers are used to improve some physical properties, mainly mechanical properties of polymers. They have found wide-spread application in the reduction of basic defects of polymers in their glassy state, mainly their resistance to low-energy impact, and they are used also to modify rheological properties of polymer melts [1].

Purin- und PyrimidinstoffwechselLight radiation contributes very actively to polymer aging, especially when oxygen is present, which is a normal situation for most plastic materials. For example, when natural rubber is exposed to UV radiation at 45°C, it oxidizes three times as fast as in the dark at 70°C [1].

Purin- und PyrimidinstoffwechselBurning of plastics presents a very serious problem that limits their application as building materials and in automobile and aviation industries, in mines, and so on. Recent disastrous accidents have raised suspicion about them in the mind of prospective users and severe safety regulations have been imposed on the plastics industry.

Koordinierung des Intermedi?rstoffwechselsto improve the properties desired of final products; this is done with minimal or no change of the polymer molecular structure. This definition excludes catalysts, initiators, cross-linking agents, and so on, which bring basic chemical changes to the polymer structure [1].

Plasticizers are used only with a limited number of polymers, the most important being poly(vinyl chloride) (PVC) and its copolymers (80% by weight [1]), cellulose deri
