Electron-induced reactive processing of polypropylene/ethylene octene copolymer blends – a new method to produce toughened polypropylene
Isotactic polypropylene has a good chemical resistance and hardness. However it has a low toughness. The blending with a rubber results in a significant increase of toughness. The main drawback of this method is a reduction of E-modulus and tensile strength. Increased values of tensile strength can be achieved by crosslinking of the rubber phase in polypropylene by high energy electrons under the dynamic conditions of melt mixing. This novel method was used for the production of toughened polypropylene. In contrast to state of the art the tensile strength of toughened polypro-pylene is comparable with that value of original polypropylene.
The Journal of Plastics Technology is a peer reviewed internet periodical published under the auspices of the Scientific Alliance of Polymer Technology (WAK)
International Polymer Processing, the journal of the Polymer Processing Society, is a discussion forum for the world-wide community of engineers and scientists in the field of polymer processing.
The journal covers research and industrial application in the very specific areas of designing polymer products, processes, processing machinery and equipment.
The Journal of Plastics Technology is indexed in SCOPUS, the largest abstract and citation database of peer-reviewed literature.
