Abstract
This article deals with influence of amount of mixing recycled material with virgin polycarbonate to impact properties. The aim is to perform an experiment in which the products of the studied polymer will be grinded to recycled material and then reprocessed into new specimens. These are then subjected to Charpy impact properties at increased temperatures. Several mixtures differing in the content of recycled material in virgin polycarbonate were prepared. One mixture was from pure recycled polycarbonate. The most used technology made testing samples for production of plastic products, which is injection moulding. Testing was conducted at increased temperatures 60 °C. This temperature was choose because many products are used at this temperatures. The impact of added recycled material to virgin polypropylene not significant for all impact properties.

The lowest measured maximum force is for the mixture with 50 % added recycled material, which is less than 6 % than the virgin polycarbonate
Summary
The significant development of the production and application of polymer materials began after massive usage of polymers. There is an increasing tendency to find possibilities for further processing and application of these secondary polymeric raw materials. Despite the increasing processing of secondary materials, there are growing demands on such made products. The work deals with the possibility of using a secondary raw material in the production of full-fledged injection products. The requirements for the material of the resulting injected product are prescribed. Secondary raw materials do not have to meet the specified values separately. On the basis of the physicalmechanical properties test, the resulting mixture could be chosen which could meet the requirements of this polymer material when is used at the elevated temperature of this product. On the basis of the physicalmechanical properties test, the resulting mixture could be chosen which could meet the requirements of this polymer material when is used at the elevated temperature of this product.
