Abstract

Polimeri predstavljaju veliku skupinu kemijskih spojeva kojima se raznim dodatcima mogu poboljšati kemijska i mehanička svojstva. Na takav se način može dobiti veliki broj tehničkih materijala širokoga područja primjene. Polimerni su materijali nezaobilazni u gotovo svakoj industriji, počevši od automobilske industrije do prehrambene. Zahvaljujući širokoj primjeni, proizvodnja polimernih materijala i želja za njihovim unaprjeđenjem je sve veća. Budući da svaka industrija ima utjecaj na okoliš, potrebno je taj utjecaj uzeti u obzir. Često se, upravo u procesima prerade polimera, oslobađaju štetne tvari koje narušavaju već ugroženi okoliš. U ovom će se radu posebna pažnja posvetiti štetnom utjecaju prerade polimera na okoliš.
Ukratko će biti opisano što su polimeri i koji su najčešći oblici njihove prerade, koji se proizvodi najčešće proizvode, kakvi se problemi u toj proizvodnji javljaju te kako smanjiti, odnosno eliminirati negativne utjecaje na okoliš.

Abstract (english)

Polymers represent a big group of chemical compounds whose chemical and mechanical properties, when enhanced with different additives, can be improved. That way a large number of technical materials can be made which serve different purposes. Polymer materials are inevitable in almost every industry, from automotive to food industry. Thanks to its wide application and tenedency for its enhancement, production of polymer materials continuously grows. Given that every industry has an impact on the environment, its impact should be taken into consideration. Oftentimes, especially in polymer processing, harmful supstances are released into the atmosphere which then violate already endangered environment. This thesis will put main focus on harmful consequences of polymer processing.
It will be described what polymers and the main types of polymer processing are, which products are the most commonly produced, which problems occur in these production processes and how to reduce and eliminate negative influences on the environment.
