Brazil-Europe Transfer of Knowledge on Polyolefin Catalyst Systems (BETRAPOCYS)
Date du début: 1 nov. 2013, Date de fin: 31 oct. 2017 PROJET  TERMINÉ 

"BETRAPOCYS is a knowledge transfer project aimed at conducting research and exchanging know-how on a new generation of bimodal polyethylene reactor blends with strongly enhanced processing characteristics and properties. The transfer of experience and skills will be secured through the exchange of researchers between Brazil and Europe, and a detailed program of courses, events and coaching. BETRAPOCYS will be carried out by three Brazilian and five European research organisations.The successful development of novel, improved polymeric materials and products from academic research to industrial practice requires an integrated Chain-of-Knowledge approach. This chain is now partly broken due to different industrial and academic foci. BETRAPOCYS aims to bridge this gap by exploiting the ultimate properties of the macromolecular knowledge chain in new sophisticated applications. The knowledge transfer programme in support of this goal consists of dedicated training courses aligned with the WPs, and common knowledge-transfer events to facilitate knowledge exchange between researchers within and outside the consortium.Bulk polyolefins are now produced using gas- and slurry phase processes with heterogeneous multi-site catalysts, allowing for good polymer particle morphology control and high bulk density without reactor fouling. However, it is more difficult to fine-tune the properties than with homogeneous single-site catalysts. The latter require immobilization to reach/exceed the same performance level; a serious challenge to be faced. BETRAPOCYS aims to study the supportation of multiple single-site catalysts onto silicate-type nano-fillers, graphene and carbon nanotubes, to produce well-processible reactor blends of tailor-made composition. The consortium will study catalyst systems, the preparation and characterisation of the bimodal blends, and the resultant properties of the systems."
