During the last 30 years the plastics industry has experienced enormous rates of growth.
Due to an increasing demand for high performance plastic materials, the use of extruders as …

The Polymeric Materials Encyclopedia presents state-of-the-art research and development
on the synthesis, properties, and applications of polymeric materials. This groundbreaking …

This work deals with the molecular characterization of maleic anhydride melt‐functionalized
polypropylene (PP‐g‐MA). The functionalization mechanism, the nature, the concentration …

An important polymer processing technique is additive manufacturing (AM), which enables
shape-free design of complex final parts with limited waste during the development change …

Ene-grafting of maleic anhydride on polypropylene previously enriched in double bonds by
β-scission was promoted in order to obtain model grafted polypropylene. Ene-grafting was …

In the present work, experimental studies of the free‐radical‐initiated molecular weight
degradation of polypropylene in a modular self‐wiping corotating twin‐screw extruder are …

The controlled-rheology peroxide degradation of polypropylene is a major issue for the
industry. Combining DFT calculations–about H-abstraction onto model 2, 4, 6 …

Results of experimental studies of free-radical-induced degradation of polypropylene (PP) in
the melt phase are presented. Experiments were carried out in a co-rotating twin-screw …

Free‐radical reactions, which are relevant in the chemical modification of polymeric
materials, are discussed in relationship to their influence on random chain scission. A …

Three series of isotactic polypropylene characterized by different molecular weights and the
same isotactic index have been studied during crystallization under static and shearing …
