Abstract

Polymers are common used in everyday life. For economic reasons and specific properties, they replace traditional materials such as glass, wood or paper. The use of polymeric materials generates waste, whose disposal is difficult. Legislation and pressures on the use of pro-ecological materials have increased interest in biodegradable polymers. Such polymers are polyhydroxyalkanoates. It is also important to use eco-friendly processing additives added to polymeric materials. The most commonly used anti – aging substances are triazine and hindered amine HALS (Hindered Amine Light Stabilizers). Most of these substances are considered to be toxic. Therefore, application of natural compounds in polymers is an interesting alternative. Polyphenols of plant origin are compounds that exhibit high reducing properties in oxidation processes. These compounds should protect polymeric materials against negative influence of environmental factors.
