A commercial isotactic polypropylene was degraded to increase its terminal vinylidene group concentration, and it was subsequently functionalized with maleic anhydride through the Alder Ene reaction at temperatures above 200Β°C in a co-rotating twin screw extruder.

## Abstract We have developed a oneβstep method for preparing nanocomposites based on powdered isotactic polypropylene (__i__βPP) as a matrix polymer (meltβflow index (MFI) = 7.2 g 10 min^β1^), oligo(__i__βPPβ__g__βMA) (MFI = 35β70 g 10 min^β1^) as a reactive compatibilizer and docecylamineβsurface
High molar mass epoxy prepolymers containing rubber dispersions based on carboxyl-terminated butadiene-acrylonitrile random copolymer (CTBN) were prepared from initially miscible solution of low molar mass epoxy prepolymers, bisphenol A and CTBN-based rubber. During chain extension inside a twin-scr
